pinctrl: add Intel BayTrail GPIO/pinctrl support

Add support for gpio on Intel BayTrail platforms. BayTrail supports 3 banks
of gpios called SCORE, NCORE ans SUS with 102, 28 and 44 gpio pins.
Supports gpio interrupts and ACPI gpio events

Pins may be muxed to alternate function instead of gpio by firmware.
This driver does not touch the pin muxing and expect firmare
to set pin muxing and pullup/down properties properly.

driver for memory mapped GPIO functionality on Intel Baytrail
platforms. Supports 3 banks with 102, 28 and 44 gpios.
Most pins are usually muxed to some other functionality by firmware,
so only a small amount is available for gpio use.
Requires ACPI device enumeration code to set up a platform device.
