Nami: Enable hibernate using silego
Nami EC has EC_HIBERNATE pin connected to a silego (U91). When this
pin is asserted, U91 shuts down ROP_PMIC_ENVR3, which turns off the
EC. Thus, we don't use the internal hibernate/wake-up feature in npcx.
BUG=b:72641658
BRANCH=none
TEST=Test system will shutdown and doesn't auto
wake up when type hibernate in ec console. And wake up by AC plugin,
LID open, or power button.
