i915: Add gen12 ids for TGL

During 5K/8K HW accelerated video playback, corruptions are observed on
gen12 TGL devices as (i915->gen <= 11) condition is returning true, and
I915_TILING_NONE tile is being set to bo. Adding gen12 ids ensures
buffer allocations happen as per the device's capabilities and here, it
resolves the video corruption issues.
