platform/x86/amd/pmf: Fix CnQF and auto-mode after resume
After suspend/resume cycle there is an error message and auto-mode
or CnQF stops working.
[ 5741.447511] amd-pmf AMDI0100:00: SMU cmd failed. err: 0xff
[ 5741.447523] amd-pmf AMDI0100:00: AMD_PMF_REGISTER_RESPONSE:ff
[ 5741.447527] amd-pmf AMDI0100:00: AMD_PMF_REGISTER_ARGUMENT:7
[ 5741.447531] amd-pmf AMDI0100:00: AMD_PMF_REGISTER_MESSAGE:16
[ 5741.447540] amd-pmf AMDI0100:00: [AUTO_MODE] avg power: 0 mW mode: QUIET
This is because the DRAM address used for accessing metrics table
needs to be refreshed after a suspend resume cycle. Add a resume
callback to reset this again.
