drm/xe: Enable media sampler power gating
Where applicable, enable media sampler power gating. Also, add
it to the powergate_info debugfs.
v2: Remove the sampler powergate status since it is cleared quickly anyway.
v3: Use vcs mask (Rodrigo) and fix the version check for media
v4: Remove extra spaces
v5: Media samplers are independent of vcs mask,
use Media version 1255 (Matt Roper)
