Fizz: Execute PMIC reset before vboot_main
When AP requests cold reboot, currently EC does not perform PMIC
reset because chipset_handle_reboot is executed only after EC jumps
to RW. This causes EC to miss CHIPSET_STARTUP and CHIPSET_RESUME
events because power rails do not cycle.
This patch will make EC execute PMIC reset to before vboot_main.
BUG=b:73093795
BRANCH=none
TEST=reboot, reboot ap-off, verify USB ports are powered after
transitionining to dev mode.
