mb/google/brya: Enable Fast VMode for brya0, skolas and skolas4es
Fast VMode nmakes the SoC throttle when the current exceeds the I_TRIP
threshold.
FSP silicon discards the request if the Voltage Regulator or SoC does
not support the feature.
BUG:b:259057787
TEST:Verify that the feature is enabled by reading from pcode
No PnP regression observed
