gru/kevin: Turn PP1800_PMU on earlier in sequence

Browse Source 
PP1800_PMU impacts the initial centerlogic voltage due to DVS circuitry.
Since there's no other sequencing dependency, turn it on earlier.
This fixes centerlogic from initially starting too high (1.5V).

BUG=none
BRANCH=none
TEST=Watch PPVAR_CENTERLOGIC and confirm that it starts at the target voltage
