mb/intel/adlrvp: Set EPP to 45% for all Adl RVP variants
This sets EPP value to be 45% for all Adl RVP variants.
Historically, EPP Ratio has always been 50% (128) on Chrome platforms.
But on Intel Alderlake EPP ratio of 45% is recommended for optimal
power and performance on Chrome platforms.
TEST=
Use 'iotools rdmsr [cpu id] 0x774' command and check field 32:24 = 0x73.
