mb/google/nissa/var/uldren: Reduce boot time for non-touchscreen sku
Non-touchscreen sku will set related GPIOs to NC. If touchscreen enabled
in overridetree for non-touchscreen sku, the boot time will be 6-7s. Set
touchscreen probed to TOUCHSCREEN_UNKNOWN for reduce boot time from 6-7s
to under 1s.
BUG=b:316434359
BRANCH=firmware-nissa-15217.B
TEST=Boot time (cbmem -t) from 6,460,972 to 922,844
