drm/amd/pm: store and reinstate swsmu user power configurations

store swsmu user power configurations which include
power limit, clock frequencies, fan speed and fan mode
on suspend and reinstate on resume.

V2: Addressed Lijo's review comments
     added a function to set clock interdependencies
     add check on fan control mode to reapply fan speed

V3: Addressed review comments from Alex
     moved store logic and reinstate function call into swSMU

V4: added a logic to keep off storing configurations in suspend

V5: Addressed review comments from Lijo
     add a restore flag
     give restore priority to mclk comparing fclk and socclk
