drivers/i2c/generic: Allow mainboards to export reset and enable GPIOs
Add power management type config option that allows mainboards to
either:
1. Define a power resource that uses the reset and enable gpios to
power on and off the device using _ON and _OFF methods, or
2. Export reset and enable GPIOs in _CRS and _DSD so that the OS can
directly toggle the GPIOs as required.
GPIO type needs to be updated in drivers_i2c_generic_config to use
acpi_gpio type so that it can be used for both the above cases.
BUG=chrome-os-partner:60194
BRANCH=None
TEST=Verified that elan touchscreen works fine on reef using exported
GPIOs.
