npcx: disable the selection of JTAG0 signals due to strap
It was observed that pressing recovery key combination + the other
keys, some keys on the keyboard become invalid after system reboots.
(see b:129908668 for more detail.)
It is because the hardware strap pin for JTAG0 signals is
unintentionally triggered. This CL reverts the selection of JTAG signals
and set them back to keyboard scan function at system initialization.
The revert applies to all real platforms except npcx_evbs.
BRANCH=none
BUG=b:129908668
TEST=pass "make buildall"
TEST=Press the specific key combination, after the system reboots,
the keyboard function works normally. On npcx EVBs, the JTAG0 is still
functional.
