mb/google/hatch/var: Increase Goodix touchscreen reset delay to 500ms
Even though GT7375P programming guide rev0.4 only requires a reset delay
of 120ms, in practice, we have to increase the reset delay to 500ms, or
Goodix FW update would fail.
This is a workaround. In the long run, we hope Goodix can fix the power
sequence in touch firmware.
BUG=b:138795891, b:138796844
TEST=boot helios board and verify Goodix FW update succeeded
