Revert "mb/intel/adlrvp: Set EPP to 45% for all Adl RVP variants"
This reverts commit 2b19d547c0866fef84bdb7b226ce7a4ac81af64f.
A power and performance analysis performed on Alder Lake demonstrated
that with an EPP (Energy Performance Preference) at 50% along with
EET (Energy Efficient Turbo) disabled, the overall SoC performance are
similar or better and the SoC uses less power.
For instance some browser benchmark results improved by 2% and some
multi-core tests by 4% while at the same time power consumption
lowered by approximately 7.6%.
BUG=b:240669428
TEST=verify that EPP is back to the by default 50% setting
`iotools rdmsr 0 0x774'
