Kevin K Wong 4d37fe58bb reef: force PMIC reset on initial boot
On EC reset where PMIC_EN will be pulled low,
PMIC could get into an unknown state and will
not sequence properly on sub-sequent boot.

This is a temporary workaround for Reef Proto,
a hardware change will be implemented on EVT.

BUG=chrome-os-partner:53974,chrome-os-partner:54507
BRANCH=none
TEST=Reef powers to S0 and starts coreboot after EC reset
     Tested with servo cold reset button
     and console reboot command
