vendorcode/google/chromeos: Get ACPI pin from GPIO library
If the generic GPIO library is enabled the code that generates the
GPIO table in ACPI should attempt to get the GPIO pin value from
the gpio_acpi_pin() function.
BUG=b:120686247
TEST=Tested on Sarien board to ensure that GPIO pin exported by
Chrome OS for the Write Protect signal is correct.
