mb/google/brya: Set EPP to 45% for all Brya variants
This sets EPP value to be 45% for all Brya 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. BUG=b:219785001 BRANCH=firmware-brya-14505.B TEST= Use 'iotools rdmsr [cpu id] 0x774' command and check field 32:24 = 0x73.
