drm/i915/tgl: Introduce gen12 forcewake ranges

Browse source

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 (Mika)
v5: bspec ref (Daniele)
