This patch series adds low power transition support for OMAP NAND driver.
[Patch 1/3]: Adds pm_runtime calls to handle GPMC module probe and remove
[Patch 2/3]: Adds GPMC suspend/resume support.
[Patch 3/3]: Adds ELM suspend/resume support.

Tested on am335x-evm with NAND flash support, using following:
	echo devices 	> /sys/power/pm_test
	echo mem	> /sys/power/state

	echo core	> /sys/power/pm_test
	echo mem	> /sys/power/state

Changes Since v3:
- CONFIG_PM -> CONFIG_PM_SLEEP
- using struct dev_pm_ops via driver->pm, instead of struct platform_driver
- rebased to 3.10-rc5

Changes Since v2:
- Remove calll back of nand_suspend from omap2 nand driver, as the same call
  already done from suspend activity mtd class driver.
