mb/google/rex/var/screebo: Set Baseline Power Limit
This patch allows google/rex mainboard to choose between "Performance"
(PL_PERFORMANCE) and "Baseline" (PL_BASELINE) power limits (PLs).
This is important for platform to meet balance between power and
performance.
The OEM design google/screebo selects baseline power limit to maintain
the balance performance in lower power.
BUG=b:307237761
