Merge branch 'amd-pstate'

Browse source 
Merge AMD P-state driver changes from Perry Yuan for v6.10:

"- Enable CPPC v2 for certain processors in the family 17H, as requested
   by TR40 processor users who expect improved performance and lower
   system temperature.

 - Change latency and delay values to be read from platform firmware
   firstly for more accurate timing.

 - A new quirk is introduced for supporting amd-pstate on legacy
   processors which either lack CPPC capability, or only only have CPPC
   v2 capability."
