Added support for the Iskratel XCEP single board computer, embedded in
instruments used in particle accelerators.

The patch contains the platform specific code, Makefile and Kconfig
changes for platform arm-pxa.

This patch configures the MFP pads for UART1, UART2, UART3 for the
Toradex Colibri PXA320 module. Previously they were just not
configured resulting in just the first UART working because it was the
only one that was configured by the bootloader (Toradex EBOOT in our
case).

This patch is against vanilla 2.6.30 and has been tested with the
Toradex Orchid carrier board (all three UARTs were functional).

Several boards use always the same pattern with pxamci :
request gpio, request irq for that gpio to detect MMC card
insertion, request gpio for read-only mode detection, etc
...

Now that pxamci provides platform_data to describe simple
gpio management of the MMC external controls, use it.

The MMC block needs 3 external datas to work :
 - is the MMC card put in "read-only mode" ?
 - is a MMC card inserted or removed ?
 - enable power towards the MMC card

Several platforms provide these controls through
gpios. Expand the platform_data to request and use these
gpios is set up by board code.

There is currently an uncovered case for MFP configuration on PXAs which
is selected by setting the PULL_SEL bit but none of the PULL{UP,DOWN}_EN
bits. This case is needed to explicitly let pins float, even if the
selected alternate function would default to a configuration with a pull
resistor enabled.
