Subject: [PATCH] drm/amdgpu/soc15: fix using ip discovery tables on renoir (v2)
The PWR block moved into SMUIO, so the ip discovery table
doesn't have an entry for PWR, but the register has the
same absolute offset, so just patch up the offsets after
updating the offsets from the IP discovery table.
v2: PWR became SMUIO block 1. fix the mapping.
