drm/amdgpu: add df perfmon regs and funcs for xgmi
v6: Squash in warning fix (Colin Ian King)
v5: Fix warnings (Alex)
v4: fixed mixed delaration and code warnings and minor errors
v3: exposing df funcs in amdgpu_df_funcs in amdgpu.h
v2: moving permonctl/perfmonctr from default to offset
- adding df perfmonctl and perfmonctr registers for df counters
- adding df funcs to set perfmonctl and get perfmonctr for
df and xgmi counters
- exposing df funcs in amdgpu_df_funcs
