soc/intel/apollolake: Add function to translate gpio_t into ACPI pin

There are four GPIO communities in this SOC and they are implemented
    as separate ACPI devices.  This means the pin number that is used in
    an ACPI GPIO declaration needs to be relative to the community that
    the pin resides in.  Also select GENERIC_GPIO_LIB in the SOC Kconfig
    so this function actually gets used.

This was tested on the reef mainboard by verifying the output of the
    SSDT for the Maxim 98357A codec that the assigned GPIO_76 is listed
    as pin 0x24 which is the value relative to the Northwest community.
