[PATCH V5 0/3] gpio: Add APM X-Gene SoC platform GPIO driver

[Feng Kan <fkan@apm.com>]

This patch add the GPIO controller in the APM X-Gene platform. The GPIO
controller pins are muxed with the generic flash controller pins on the 
system.

V5 Change:
	1. Remove gpio->dev
	2. Remove not needed headers. 
	3. Change to use latest driver.h for gpio.
	4. Set chip base to -1
	5. Put back label as it is needed sys interface.

V4 Change:
	1. Add remove function for module
	2. Add set function to dir out function.
	3. remove sets to np and label in probe.

V3 Change:
	1. Change code to use single entry to describe gpio node, hardcode
	   to use bank stride to target gpios.
	2. Fix up dts and doc accordingly

V2 Change:
	1. Address concerns from maintainer, split to multiple device node
	2. Add pm code to restore set register.
	3. fix up dts and documentation accordingly.

I did not incorporate pin mux functionality at this time, move this to
bootloader for now. Will submit pinctrl driver seperately.
