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.
V6 Change:
1. change attribute description of second cell in gpio dts node
under documentation.
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.
