This implements cros_rtc_npcx driver for Zephyr OS-based EC. For the
NPCX7 chip, NPCX Monotonic Counter(MTC) provides a time-keeping
function with a resolution of one second. MTC is selected to implement
the cros_rtc_npcx driver.
BUG=b:178230662
BRANCH=None.
TEST=zmake testall

NPCX keyboard scanning module is supported by up to 18 open-drain
output signals and 8 input signals. Switch-based keyboard matrices are
supported by Schmitt trigger inputs that have internal pull-up
resistors. For power efficiency, the inputs include interrupt and
wake-up capability so that pressing/releasing keys can be identified
without scanning the keyboard matrix in either Active, Sleep or Deep
Sleep power state.
The CL also includes:
— Add npcx cros_kb_raw device tree declarations.
— cros_kb_raw api implementations
- Enable Volteer keyboard scan task
BRANCH=none
BUG=b:167405015, b:172676906
TEST=build pass by zmake configure -B ./build projects/experimental/volteer.
TEST=check all the keys on volteer platform by "ksstate".
