Amber Lin e5a6702e51 drm/amdkfd: Set TG_CHUNK_SIZE for GC 9.4.3
On GC 9.4.3, DW 41 in MQD is repurposed as compute_tg_chunk_size
for cooperative dispatch. When it's a AQL queue, set compute_tg_chunk_size
as 1 to spread work groups evenly among XCCs. If it's PM4 queue, unset
compute_tg_chunk_size to disable cooperative mode.

v3: set compute_tg_chunk_size as 1 instead of #CUs per XCC
v2: set compute_tg_chunk_size as #CUs per XCC instead of total wave
slots per XCC
