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.
