drm/i915: Update gen12 forcewake table
The bspec's forcewake page was very stale and out of date for recent platforms. The hardware team finally provided us with an updated gen12 table (which applies to TGL, RKL, and DG1) and there are a lot of changes. v2: - Add comments showing the subregions of ranges that we've combined for ease of code review. (Jose) - Rebase on the s/FORCEWAKE_BLITTER/FORCEWAKE_GT/ patch Bspec: 66696 Cc: Caz Yokoyama <caz.yokoyama@intel.com> Cc: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Cc: José Roberto de Souza <jose.souza@intel.com> Signed-off-by: Matt Roper <matthew.d.roper@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20201009194442.3668677-3-matthew.d.roper@intel.com Reviewed-by: José Roberto de Souza <jose.souza@intel.com>
