The mxs pinctrl driver will only support DT probe.  That said, the mxs
device drivers can only get pinctrl state from pinctrl subsystem when
the drivers get probed from device tree.

Before converting the whole mxs platform support over to device tree,
we need to enable pinctrl dummy states for those non-DT board files
to ensure the pinctrl API adopted by mxs device drivers will work for
both DT and non-DT probe.

Instead of calling pinctrl_provide_dummies() directly in every board
file, the patch introduces soc specific calls mx23_soc_init() and
mx28_soc_init() for boards' .init_machine hook to invoke, so that
any soc specific setup for non-DT boot only can be added there.

Currently, the MAC address from the second ethernet is generated from the
crypto-key (and not a customer reg) because of a wrong index to the ocotp

The merge commit "526b2641 Merge branch 'imx/cleanup' into imx/devel"
left a duplicated mx28_add_mxs_mmc() call, which causes the problem
below during boot.

  kobject_add_internal failed for mxs-mmc.1 with -EEXIST, don't try
  to register things with the same name in the same directory.

The patch removes this leftover and also change mmc0 adding to align
with mmc1.

GPIO drivers are getting moved to drivers/gpio for cleanup and
consolidation.  This patch moves the mxs driver.  Follow up patches
will clean it up and make it a fine upstanding example of a gpio
driver.

v2: Removed header file entirely and put struct definition directly
    into driver.  The struct isn't used anywhere else in the kernel.
