staging: greybus: Add TODO file with GPIO work items 

To make sure that these drivers do not leave staging before they
are properly converted to use the new GPIO descriptor API, and the
GPIOLIB_IRQCHIP helper library, create the TODO file with these work
items.

* Convert all uses of the old GPIO API from <linux/gpio.h> to the
GPIO descriptor API in <linux/gpio/consumer.h> and look up GPIO
lines from device tree or ACPI.
* Convert the GPIO driver to use the GPIO irqchip library
GPIOLIB_IRQCHIP instead of reimplementing the same.
