drm/amdgpu: disable XNACK replay for all VMIDs on GC 12.1.0 A0

Browse source

XNACK is not supported on A0. Updating RETRY_DISABLE only for the VMID
in use gives unreliable control, so all VMIDs must be programmed
identically.

Set SH_MEM_CONFIG.RETRY_DISABLE = 1 on rev_id 0 for every VMID in both
constants init and compute VMID init, so XNACK replay is off from device
boot up.
