drm/xe: Carve out wopcm portion from the stolen memory
[ Upstream commit e977499820782ab1c69f354d9f41b6d9ad1f43d9 ]
The top of stolen memory is WOPCM, which shouldn't be accessed. Remove
this portion from the stolen memory region for discrete platforms.
This was already done for integrated, but was missing for discrete
platforms.
This also moves get_wopcm_size() so detect_bar2_dgfx() and
detect_bar2_integrated can use the same function.
v2: Improve commit message and suitable stable version tag(Lucas)
Fixes: d8b52a02cb40 ("drm/xe: Implement stolen memory.")
