drm/amdkfd: Adjust CWSR trap handler for gfx950

Browse source

In gfx950, the SQ_WAVE_LDS_ALLOC.LDS_SIZE field is extended to bits 12
to 22.  The LDS_SIZE granularity remains unchanged (units of 64 dwords,
or 256 bytes).  This patch adjusts the CWSR trap handler to read the
full extent of LDS_SIZE.
