zephyr: npcx: Add non-psl hibernate implementation
Implements non-psl hibernate mechanism for cros_system driver. First,
we plan a little hibernate function locates in the last 32K ram block
in npcx7 series. Then power down the other ram blocks and go to deep
sleep mode for better power consumptions.
Please notice do not use global or call the other functions in this
hibernate utility since we have turned off the other ram blocks.
BUG=b:177904393, b:183745774
BRANCH=none
TEST=zmake testall
TEST=All wake-up GPIOs can wake-up ec from hibernating on npcx7 evb.
