drm/amd/pm/ci: Fill DW8 fields from SMC

Browse Source 
In ci_populate_dw8() we currently just read a value from the SMU
and then throw it away. Instead of throwing away the value,
we should use it to fill other fields in DW8 (like radeon).

Otherwise the value of the other fiels is just cleared when
we copy this data to the SMU later.

Fixes: 9f4b35411c ("drm/amd/powerplay: add CI asics support to smumgr (v3)")
