Add stepping-substepping info. Though it looks
weird, the revision ID for the newer stepping
is indeed backwards and is in accordance to the spec.

i915 now uses full names for platforms. So we now have
ALDERLAKE instead of ADL. Extend this to xe driver as well.
This will make it easier for macro magic usages.
v2: Do not make changes to compat-i915-headers/i915_drv.h

If the GMD_ID register reports a higher media revision ID than we're
expecting, print the media revid, not the graphics revid, in the
debug message.

For platforms with GMD_ID registers, the IP stepping should be
determined from the 'revid' field of those registers rather than from
the PCI revid.
The hardware teams have indicated that they plan to keep the revid =>
stepping mapping consistent across all GMD_ID platforms, with major
steppings (A0, B0, C0, etc.) having revids that are multiples of 4, and
minor steppings (A1, A2, A3, etc.) taking the intermediate values. For
now we'll trust that hardware follows through on this plan; if they have
to change direction in the future (e.g., they wind up needing something
like an "A4" that doesn't fit this scheme), we can add a GMD_ID-based
lookup table when the time comes.
v2:
- Set xe->info.platform before finding stepping; the pre-GMD_ID code
relies on this value to pick a lookup table.
v3:
- Also set xe->info.subplatform before picking the stepping for
pre-GMD_ID lookup.

ADL-N is pretty much the same as ADL-P (i.e., Xe_LP graphics + Xe_M
media + Xe_LPD display). However unlike ADL-P, there's no GuC hwconfig
support so the "tgl" GuC firmware should be loaded (i.e., the same
situation as ADL-S).

Setup the mapping from PCI revid to IP stepping for ADL-P (and its RPL-P
subplatform) in case this information becomes important for implementing
workarounds.

The PVC pre-production A* steppings are not going to be supported in xe
driver - the steppings are important for the WAs and since we are not
adding the pre-productions ones, there is no need to add the stepping.

Reduce the use of i915_reg_defs.h so it can be encapsulated in a single
place.
1) If it was being included by mistake, remove
2) If it was included for FIELD_GET()/FIELD_PREP()/GENMASK() and the
like, just include <linux/bitfield.h>
3) If it was included to be able to define additional registers, move
the registers to the relavant headers (regs/xe_regs.h or
regs/xe_gt_regs.h)
v2:
- Squash commit fixing i915_reg_defs.h include and with the one
introducing regs/xe_reg_defs.h
- Remove more cases of i915_reg_defs.h being used when all it was
needed was linux/bitfield.h (Matt Roper)
- Move some registers to the corresponding regs/*.h file (Matt Roper)

[Rodrigo squashed here the removal of the i915 include]

Xe, is a new driver for Intel GPUs that supports both integrated and
discrete platforms starting with Tiger Lake (first Intel Xe Architecture).
The code is at a stage where it is already functional and has experimental
support for multiple platforms starting from Tiger Lake, with initial
support implemented in Mesa (for Iris and Anv, our OpenGL and Vulkan
drivers), as well as in NEO (for OpenCL and Level0).
The new Xe driver leverages a lot from i915.
As for display, the intent is to share the display code with the i915
driver so that there is maximum reuse there. But it is not added
in this patch.
This initial work is a collaboration of many people and unfortunately
the big squashed patch won't fully honor the proper credits. But let's
get some git quick stats so we can at least try to preserve some of the
credits:
