gpio: split gpiod board registration into machine header 



As per example from the regulator subsystem: put all defines and
functions related to registering board info for GPIO descriptors
into a separate <linux/gpio/machine.h> header.

Finally, GPIOs can be bound to devices and functions using platform data. Board

files that desire to do so need to include the following header:



	#include <linux/gpio/driver.h>

	#include <linux/gpio/machine.h>



GPIOs are mapped by the means of tables of lookups, containing instances of the

gpiod_lookup structure. Two macros are defined to help declaring such mappings:
