drivers/spi/acpi: Add additional generic ACPI support

Add support for more ACPI features in the generic SPI ACPI
    driver so it can be flexible enough to support more devices,
    or devices in different configurations.

- add a wake pin
    - add support for using IRQ GPIO instead of PIRQ
    - add power resource support with enable and reset gpios

BUG=chrome-os-partner:61233
    TEST=ensure existing SSDT generation is unchanged,
    and test that new features generate expected code
