mb/google/hatch: Set GPP_D9 as enable pin for Goodix Touch Screen and
increase reset off delay time
Goodix touchscreen cannot work in normal mode because PP3300_TOUCHSCREEN_DX
dropped. Configure GPP_D9 as enable pin in the devicetree.cb to fix the power
sequence. Increase reset_off_delay time from 1ms to 3ms to met the HW requirement.
BUG=b:135287161
BRANCH=None
TEST=local build and measure sequence with Goodix touch screen
