drm/amdkfd: Update LDS, Scratch base for 57bit address

Browse source

For 5-level page tables, update compute vmid sh_mem_base LDS aperture
and Scratch aperture base address to above 57-bit, use the same setting
from gfx vmid, we can remove the duplicate macro.

Update queue pdd lds_base and scratch_base to the same value as
sh_mem_base setting. Then application get process apertures return the
correct value to access LDS and Scratch memory for 57bit address 5-level
page tables. This may pass to MES in future when mapping queue.
