mb/google/kohaku: Update reset_delay_ms for digitizer device 

We found the driver binding failure issue could be cleared with 100ms
of "reset_delay_ms". Needs further check with device vendor, anyway it
seems the IC need some time before communication after de-assertion of
reset.

BUG=b:129159369
BRANCH=firmware-hatch-12672.B
TEST=Verified driver bound successfully.
