mb/google/dedede/var/shotzo: Enable ILITEK touchscreen
The current reset delay is not enough to make touchscreen IC ready,
ILITEK feedback their requiremt is 400ms in spec T2.
After changing the reset_delay_ms and check touchscreen works,
ILITE also change the IRO to low level trigger.
This CL is to reflect that.
