rambi: Enable PP5000 at boot
Due to power topology, PP5000 needs to be enabled as soon after
PP3300_DSW as possible. Since PP3300_DSW is what powers the EC, the
EC needs to turn on PP5000 by default and leave it on.
BUG=chrome-os-partner:23673
BRANCH=none
TEST=reboot ap-off (this boots the EC without doing AP power sequencing)
gpioget -> shows PP5000_EN=1, PP5000_GOOD=1
