drm/xe/xe2hpg: Remove extra allocation of CCS pages for dgfx
On Xe2 dGPU, compression is only supported with VRAM. When copying from
VRAM -> system memory the KMD uses mapping with uncompressed PAT
so the copy in system memory is guaranteed to be uncompressed.
When restoring such buffers from system memory -> VRAM the KMD can't
easily know which pages were originally compressed, so we always use
uncompressed -> uncompressed here.
so this means that there's no need for extra CCS storage on such
platforms.
v2: More description added to commit message
