Ponte Vecchio no longer has MSLICE or LNCF steering, but the bspec does
document several new types of multicast register ranges. Fortunately,
most of the different MCR types all provide valid values at instance
(0,0) so there's no need to read fuse registers and calculate a
non-terminated instance. We'll lump all of those range types (BSLICE,
HALFBSLICE, TILEPSMI, CC, and L3BANK) into a single category called
"INSTANCE0" to keep things simple. We'll also perform explicit steering
for each of these multicast register types, even if the implicit
steering setup for COMPUTE/DSS ranges would have worked too; this is
based on guidance from our hardware architects who suggested that we
move away from implicit steering and start explicitly steer all MCR
register accesses on modern platforms (we'll work on transitioning
COMPUTE/DSS to explicit steering in the future).
Note that there's one additional MCR range type defined in the bspec
(SQIDI) that we don't handle here. Those ranges use a different
steering control register that we never touch; since instance 0 is also
always a valid setting there, we can just ignore those ranges.
Finally, we'll rename the HAS_MSLICES() macro to HAS_MSLICE_STEERING().
PVC hardware still has units referred to as mslices, but there's no
register steering based on mslice for this platform.
v2:
- Rebase on other recent changes
- Swap two table rows to keep table sorted & easy to read. (Harish)

As a side effect of the of removal this flag, it will not be printed

[Fixed conflicts while applying, using the fixups/drm-intel-gt-next.patch
from drm-rerere's 1f2b1742abdd ("2022y-02m-23d-16h-07m-57s UTC: drm-tip
rerere cache update")]
In the past we had a need to differentiate TGL U and TGL Y, there
was a different voltage swing table for each subplatform and some PCI
ids of this subplatforms are shared but it turned out that it was a
specification mistake and the voltage swing table was indeed the same
but we went ahead with that patch because we needed to differentiate
TGL U and Y from TGL H and by that time TGL H was embargoed so that
was the perfect way to land it upstream.
Now the embargo for TGL H is long past and now we even have
INTEL_TGL_12_GT1_IDS with all TGL H ids, so we can drop this PCI root
check and only rely in the PCI ids to differentiate TGL U and Y from
TGL H that actually has code differences.
Besides the simplification this will fix issues in virtualization
environments where the PCI root is virtualized and don't have the same
id as actual hardware.
v2:
- add and set INTEL_SUBPLATFORM_UY
