Nicolai Hähnle 559121f5a1 drm/amdgpu: set COMPUTE_PGM_RSRC1 for SGPR/VGPR clearing shaders
commit 75569c182e upstream.

Otherwise, the SQ may skip some of the register writes, or shader waves may
be allocated where we don't expect them, so that as a result we don't actually
reset all of the register SRAMs. This can lead to spurious ECC errors later on
if a shader uses an uninitialized register.
