Duncan Laurie c97c8904b7 UPSTREAM: gpio: Add a function to map GPIO to ACPI path 
Add a new function "gpio_acpi_path()" that can be implemented by
SoC/board code to provide a mapping from a "gpio_t" pin to a
controller by returning the ACPI path for the controller that owns
this particular GPIO.

This is implemented separately from the "acpi_name" handler as many
SOCs do not have a specific device that handles GPIOs (or may have
many devices and the only way to know which is the opaque gpio_t)
and the current GPIO library does not have any association with the
device tree.

If not implemented (many SoCs do not implement the GPIO library
abstraction at all in coreboot) then the default handler will return
NULL and the caller knows it cannot determine this reliably.

BUG=None
BRANCH=None
TEST=None
