[patch v4 00/10] efikamx support improvements - take 4

[Arnaud Patard (Rtp)]

Hi,

This patchset aims at improving current efikamx support. It adds support for :
- board id detection
- sdhc
- leds
- power button
- spi nor
- reset

I also had to fix/improve some imx51 iomux header so there are patches for
iomux-mx51.h.

v4:
- reorder selects for the machine Kconfig entry
- drop linux/gpio_keys.h include
- mark mx51_efikamx_powerkey_data as const & __initconst
- add missing return after calling mx51_efikamx_reset()

v3:
- use imx51_add_gpio_keys
- fix patch description for power key patch

v2:
- split iomux patch 3 into 2 patches
- reorder patches
- fix space comment
- fix Amit's comments
- decrease board id msleep
