arch/x86/acpigen: Provide helper functions for enabling/disabling GPIO

In order to allow GPIOs to be set/clear according to their polarity,
    provide helper functions that check for polarity and call set/clear
    SoC functions for generating ACPI code.

    BRANCH=None
    TEST=Verified that the ACPI code generated remains the same as before
    for reef.
