mb/google/rex/var/rex0: Toggle NVMe PWR pin to reset SSD

During warm reboot, NVMe is not detected with non-serial image
sometimes while there is no issue with serial image. This change
toggles NVMe PWR pin as soon as in early stage to make NVMe ready
sooner.

BUG=b:260547988
BRANCH=None
TEST= Build rex0 and try warm reboot from OS console. Check if
the platform with Micron SSD boots to OS again without an issue.
