amd/registers: fix fields conflict detection
The existing code handled the case where the new definition of the same field was larger than the old one. This commit adds a check to handle the reverse case: the new def is smaller than the old one (= so writing using the merged macro would affect the next fields). The affected fields are: * LGKM_CNT (in SQ_WAVE_IB_STS) * DONUT_SPLIT (in VGT_TESS_DISTRIBUTION) * HEAD_QUEUE (in GDS_GWS_RESOURCE) DONUT_SPLIT is the only one used by radeonsi/radv.
