mb/google/fatcat: Disable package c-state auto-demotion
Package C-state auto demotion feature allows hardware to determine lower
C-state as per platform policy. Since platform sets performance policy
to balanced from hardware, auto demotion can be disabled without
performance impact.
TEST=Build fatcat and check the platform boots without an issue.
