Make a xe_mem_region structure which will be used in the
coming patches. The new structure is used in both xe device
level (xe->mem.vram) and xe_tile level (tile->vram).
Make the definition of xe_mem_region.dpa_base to be the DPA
base of this memory region and change codes according to
this new definition.
v1:
