[PATCH 01/13] drm/amdkfd: Skip pairwise CU mask check for GFX12.1

From: Mukul Joshi <[email protected]>

GFX12.1 doesn't follow the pair-wise CU mask requirement as
is the case for GFX 10,GFX 11 and GFX 12.
Currently, the ioctl call is returning error because of this
incorrect condition of checking for a pair of CUs to be enabled
in the CU mask.
Fix the issue by removing this check for GFX 12.1.
