Create a platform device for each IPMI device in the DMI table,
a separate kind of device for SSIF types and for KCS, BT, and
SMIC types. This is so auto-loading IPMI devices will work
from just SMBIOS tables.
This also adds the ability to extract the slave address from
the SMBIOS tables, so that when the driver uses ACPI-specified
interfaces, it can still extract the slave address from SMBIOS.

The registers for the bt-bmc device live under the Aspeed LPC
controller. Devicetree bindings have recently been introduced for the
LPC controller where the "host" portion of the LPC register space is
described as a syscon device. Future devicetrees describing the bt-bmc
device should nest its node under the appropriate "simple-mfd", "syscon"
compatible node.
This change allows the bt-bmc driver to function with both syscon and
non-syscon- based devicetree descriptions by always using a regmap for
register access, either retrieved from the parent syscon device or
instantiated if none exists.

This patch adds a simple device driver to expose the iBT interface on
Aspeed SOCs (AST2400 and AST2500) as a character device. Such SOCs are
commonly used as BMCs (BaseBoard Management Controllers) and this
driver implements the BMC side of the BT interface.
The BT (Block Transfer) interface is used to perform in-band IPMI
communication between a host and its BMC. Entire messages are buffered
before sending a notification to the other end, host or BMC, that
there is data to be read. Usually, the host emits requests and the BMC
responses but the specification provides a mean for the BMC to send
SMS Attention (BMC-to-Host attention or System Management Software
attention) messages.
For this purpose, the driver introduces a specific ioctl on the
device: 'BT_BMC_IOCTL_SMS_ATN' that can be used by the system running
on the BMC to signal the host of such an event.
The device name defaults to '/dev/ipmi-bt-host'

Parameter trydefaults=1 causes the ipmi_init to initialize ipmi through
the legacy port io space that was designated for ipmi. Architectures
that do not map legacy port io can panic when trydefaults=1.
Rather than implement build-time conditional exceptions for each
architecture that does not map legacy port io, we have removed legacy
port io from the driver.
Parameter 'trydefaults' has been removed. Attempts to use it hereafter
will evoke the "Unknown symbol in module, or unknown parameter" message.
The patch was built against a number of architectures and tested for
regressions and functionality on x86_64 and ARM64.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
