[PATCH 1/1] drm/xe/xe2: Separate graphics_xe2 features to hpg and lpg

[Juha-Pekka Heikkila]

Separate graphics_xe2 to graphics_xe2hpg and graphics_xe2lpg. This is done to
be able to add XE_VRAM_FLAGS_NEED64K for xe2hpg. Without 64K pages xe2hpg
ccs decompression can result in corruption on display.
