drm/amdgpu: set COMPUTE_PGM_RSRC1 for SGPR/VGPR clearing shadersamd-18.10
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.
