OCPC: Init VSYS to VBAT when starting charge
In order to prevent high current spikes when the OCPC PID loop runs,
this commit sets the initial VSYS voltage to that of the battery.
BUG=b:175334490
BRANCH=dedede
TEST=Build and flash DUT. Using a Type-C breakout board and a current
probe, plug in charger to sub board, verify that no initial current
spike exceeds that of the contract.
