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 Signed-off-by: Philip Chen <philipchen@google.com> Change-Id: Ic0049bf240de0a1c7f1b1f39bf155d48bb76fb86 Reviewed-on: https://review.coreboot.org/c/coreboot/+/35350 Reviewed-by: Furquan Shaikh <furquan@google.com> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
