Herobrine uses the SPI mux to separate the SPI bus from the AP when
programming the AP firmware. Overdriving signals on WARM_RESET is not
needed. Make the WARM_RESET and POWER_GOOD GPIOs like normal power
signals.
BRANCH=None
BUG=b:187098628
TEST=Booted AP properly. Flashed the AP firmware, even AP is off.

This CL is a Zephyr-equivalent of CL:2993217.
Update the GPIOs to match the schematic. Also update the hibnerate
wake sources. Remove the AP_RST_L and WARM_RESET_L from the low voltage
dts as their new GPIOs already operate at 1.8V, not configurable.

This CL copies the Zephyr board/trogdor to board/herobrine_npcx9.
Modify the chip config to npcx9m3f and some related configs (simply
rename) and dts (update the UART property). The board/herobrine_npcx9
and other NPCX9 boards, like board/brya will be merged to a single
board. But the merge needs more work to remove the not-common configs
and dts to the project directories. Leave it as a future work.
This CL also copies the project trogdor/herobrine_npcx7 to
herobrine/herobrine_npcx9. Remove the dead files power.c and
hibernate.c, in the EC-OS directory. Remove the Zephyr 2.5 support
and board.cmake (needed only for 2.5).
