drm/amdkfd: add sdma queue counter for gfxv9.4.3
since gfx 9.4.3 HW is calculating accumulated activity counter
per-queue in register sdmax_rlcx_utilization_hi/lo, CPFW adds it in
sdma MQD for save/restore, KFD will read it from there. gfx 9.4.2
will still keep the way to read from memory at rptr+8.
v2: read dynamic counter directly from utilization register
v3: add CPFW supported version check (Harish)
