mb/google/dedede/var/waddledoo: Configure stop delay for SiS TS
Reset the Touchscreen (TS) and disable the stop GPIO (report switch) at
the same time. Add a delay of 100 ms after disabling the stop GPIO. This
will ensure the required delay is inserted for both reset and stop
disable GPIOs simultaneously.
BUG=b:152936541
TEST=Build and boot the waddledoo mainboard. Ensure that the SiS
Touchscreen is functional.
