mb/google/eve: Remove ACPI control of touchscreen power
Change the touchscreen power control back to coreboot instead of
under the ACPI _ON/_OFF methods, and switch the TOUCHSCREEN_STOP_L
pin back to an output.
This reverts previous changes to touchscreen GPIOs that were made
to get back to a known good/working state. Having ACPI control these
pins was resulting in a small percentage of touchscreen not being
discovered at boot. This platform is not intending to use S0ix so
the ACPI control is not needed.
BUG=b:63718744
TEST=manual testing on Eve devices.
