From: Michel Thierry <michel.thierry@intel.com>

The media ranges extend beyond what gen11 gives so we can't piggypack
on gen11 ranges, even on read side.

Introduce a table for gen12 and accessors for it.

v2: correctly implement gen12_fwtable_write/read (Daniele)
v3: update with ranges from bspec.
v4: avoid GEN11_NEEDS_FORCEWAKE on read size (Mika)

BSpec: 18331.

From: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com>

Gen12 has dual-subslices (DSS), which compared to gen11 subslices have
some duplicated resources/paths. Although DSS behave similarly to 2
subslices, instead of splitting this and presenting userspace with bits
not directly representative of hardware resources, present userspace
with a subslice_mask made up of DSS bits instead.

v2: GEM_BUG_ON on mask size (Lionel)

After this I get the correct values for TGL:
-  Available Subslice Total: 2
-  Available Slice0 subslices: 2
-  Available EU Total: 16
-  Available EU Per Subslice: 8
+  Available Subslice Total: 6
+  Available Slice0 subslices: 6
+  Available EU Total: 96
+  Available EU Per Subslice: 16
