keyboard_scan: Add option to support keyboards with language ID
ID pins are considered additional KSOs while keycode scanning works
for the existing KSI0 ~ KSI7. While diriving ID pins, the state of
interconnection between ID pins and KSI pins could be used for
identifiers to tell keyboard itself. (e.g. US, Japan,and UK keyboard)
BRANCH=master
BUG=b:80168723
TEST="make -j buildall"
TEST=Verified 5 distinct keyboard samples w/ different Language ID values
on the same reworked Coral, which VOL_UP and VOL_DOWN were reworked
for ID pins. crrev.com/c/1053617 is my experimental patch on top of
this for further verification
