mb/google/hatch: Kohaku: Add touchscreen controller to device tree
The touchscreen controller was never added to the device tree, and the
next board rev will have this IC connected. Set it up in the device tree
with conservative power resource timings from the datasheet.
BUG=b:138869702
BRANCH=none
TEST=compiles; current board rev does not have touch IC
