brya: Enable EC hibernate using PSL
This adds the wake source pin definitions needed by the NPCX9 chip
support code for brya board ID 1. Note that board ID 1 needs a rework on
VCC1_RST to prevent it from falsely waking the board.
BRANCH=none
BUG=b:183246197
TEST=booted same image on old and new rev. of board
Used "hibernate" on EC console hibernate the system. It woke
up immediately (b/183412004) with cause "hibernate" indicating
this was a PSL wake:
--- UART initialized after reboot ---
[Image: RO, brya_v2.0.8357-19a8f337db 2021-04-08 01:09:30 caveh@caveh]
[Reset cause: power-on hibernate wake-pin]
LID_OPEN was tested as a PSL wake source by artificially disabling
CONFIG_HIBERNATE_PSL_VCC1_RST_WAKEUP to eliminate VCC1 as a false
wake source.
