The core infrastructure has everything in place to switch ICU to per
device MSI domains and avoid the convoluted construct of the existing
platform-MSI layering violation.
The new infrastructure provides a wired interrupt specific interface in the
MSI core which converts the 'hardware interrupt number + trigger type'
allocation which is required for wired interrupts in the regular irqdomain
code to a normal MSI allocation.
The hardware interrupt number and the trigger type are stored in the MSI
descriptor device cookie by the core code so the ICU specific code can
retrieve them.
The new per device domain is only instantiated when the irqdomain which is
associated to the ICU device provides MSI parent functionality. Up to
that point it invokes the existing code. Once the parent is converted the
code for the current platform-MSI mechanism is removed.
The new domain shares the interrupt chip callbacks and the translation
function. The only new functionality aside of filling out the
msi_domain_templates is a domain specific set_desc() callback, which will go
away once all platform-MSI code has been converted.

The MBI chip creates two MSI domains:
- PCI/MSI
- Platform device domain
Both have the MBI domain as parent and differ slightly in the interrupt
chip callbacks and the platform device domain supports level type
signaling.
Convert it over to the MSI parent domain mechanism by:
- Providing the required templates
- Implementing a custom init_dev_msi_info() callback which sets the chip
callbacks and the level support flags depending on the domain bus token
type of the per device domain.

The its_pci_msi_prepare() function from the ITS-PCI/MSI code provides the
'global' PCI/MSI domains. Move this function to the ITS-MSI parent code and
amend the function to use the domain hardware size, which is the MSI[X]
vector count, for allocating the ITS slots for the PCI device.
Enable PCI matching in msi_parent_ops and provide the necessary update to
the ITS specific child domain initialization function so that the prepare
callback gets invoked on allocations.
The latter might be optimized to do the allocation right at the point where
the child domain is initialized, but keep it simple for now.

To support per device MSI domains the ITS must provide MSI parent domain
functionality.
Provide the basic skeleton for this:
- msi_parent_ops
- child domain init callback
- the MSI parent flag set in irqdomain::flags
This does not make ITS a functional parent domain as there is no bit set in
the bus_select_mask yet, but it provides the base to implement PCI and
platform MSI support gradually on top.

All irqdomains which provide MSI parent domain functionality for per device

function to initialize the child domain.
Most of these functions would just be copy&paste with minimal
modifications, so provide a library function which implements the required
functionality and is customizable via parent_domain::msi_parent_ops. The
check for the supported bus tokens in msi_lib_init_dev_msi_info() is

Most ARM(64) PCI/MSI domains mask and unmask in the parent domain after or
before the PCI mask/unmask operation takes place. So there are more than a
dozen of the same wrapper implementation all over the place.
Don't make the same mistake with the new per device PCI/MSI domains and
provide a new MSI feature flag, which lets the domain implementation
enable this sequence in the PCI/MSI code.

- Default silead touchscreen driver to 10 fingers and drop 10 finger
setting from all DMI quirks. More of a cleanup then a pure fix, but
since the DMI quirks always get updated through the fixes branch
this avoids conflicts.

The Elan eKTH5015M touch controller found on the Lenovo ThinkPad X13s
shares the VCC33 supply with other peripherals that may remain powered
during suspend (e.g. when enabled as wakeup sources).
The reset line is also wired so that it can be left deasserted when the
supply is off.
This is important as it avoids holding the controller in reset for
extended periods of time when it remains powered, which can lead to
increased power consumption, and also avoids leaking current through the
X13s reset circuitry during suspend (and after driver unbind).
Use the new 'no-reset-on-power-off' devicetree property to determine
when reset needs to be asserted on power down.
Notably this also avoids wasting power on machine variants without a
touchscreen for which the driver would otherwise exit probe with reset
asserted.

When the power supply is shared with other peripherals the reset line
can be wired in such a way that it can remain deasserted regardless of
whether the supply is on or not.
This is important as it can be used to avoid holding the controller in
reset for extended periods of time when it remains powered, something
which can lead to increased power consumption. Leaving reset deasserted
also avoids leaking current through the reset circuitry pull-up
resistors.
Add a new 'no-reset-on-power-off' devicetree property which can be used
by the OS to determine when reset needs to be asserted on power down.
Note that this property can also be used when the supply cannot be
turned off by the OS at all.

Add a compatible string for the Elan eKTH5015M touch controller.
Judging from the current binding and commit bd3cba00dc ("HID: i2c-hid:
elan: Add support for Elan eKTH6915 i2c-hid touchscreens"), eKTH5015M
appears to be compatible with eKTH6915. Notably the power-on sequence is
the same.
While at it, drop a redundant label from the example.

The Ilitek ILI2901 touch screen controller was apparently incorrectly
added to the Elan eKTH6915 schema simply because it also has a reset
gpio and is currently managed by the Elan driver in Linux.
The two controllers are not related even if an unfortunate wording in
the commit message adding the Ilitek compatible made it sound like they
were.
Add a dedicated schema for the ILI2901 which does not specify the I2C
address (which is likely 0x41 rather than 0x10 as for other Ilitek touch
controllers) to avoid cluttering the Elan schema with unrelated devices
and to make it easier to find the correct schema when adding further
Ilitek controllers.
