keyboard_scan: Add "ksstate force" to always scan KB matrix
For early bringup, or failure analysis, it is sometimes useful to
be able to force enable the keyboard matrix scanning, even though
other signals (lid close, usb off) would normally disable it.
The only way to disable the scanning again is to wait for an
lid/USB event, or reboot the board, which is ok as this is
for debugging purpose only.
BRANCH=none
BUG=b:109743721
TEST=Provide power to whiskers via servo only.
ksstate force => key presses are shown
