This patch series adds low power transition support for OMAP NAND driver.
With recent driver conversion of GPMC to platform_driver, pm_runtime calls
can be used to handle module enable & disable of GPMC. This is taken care
patch #1.

patch #2 is for GPMC suspend/resume support.

This includes low power transition support of
- GPMC module
- ELM module

User initiated suspend/resume sequence tested on am335x-evm with NAND
flash support. Also tested in omap3-evm for user initiated
suspend/resume sequence with NAND flash.
This patch series based on [1] and is present in [2].

1. ARM: OMAP2+: AM33XX: Add suspend-resume support

2. https://github.com/avinashphilip/am335x_linux/commits/NAND_supend_resume_support

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.
