mx3fb.c calls disable_irq() from a DMA callback, i.e., in an IRQ-handler
context, which has always been unsafe, and became deadly after the merge of
threaded interrupt handler support. Use disable_irq_nosync() instead.

This adds the camera device based on Guennadi's soc_camera architecture
for the mx31.
The proposed init by Guennadi was removed and must be implemented in the
board init file as it contains a lot of board specific info (memory
size, clock speed).

In order to use the gpiolib, we now have to call gpio_request in
the plaform code since it is not done in iomux code anymore.

Since iomux code is not directly related to gpio on mx31, the calls
to gpio_request are removed from iomux.c file.
These calls have to be done in platform initialization files. The
name of the singe pin call for iomux is also changed to
mxc_iomux_alloc_pin.

sdhc2 is present on both, but is not directly included in the
mx31moboard file because a third baseboard (not supported yet) without
sdhc2 is planned.

It is no longer present in newer cores. Unfortunately Freescale decided
to put the bit which decides between automotive clock path and consumer
clock path in the automotive clock path direction. With current code we
cannot detect the core revision, so just remove automotive path completely.
