ARM: rename STM arch to mxs ...

We never supported the sigmatel stm chips and probably
never will. So do the first step and rename the architecture
to mxs just like in the kernel.

Add GPIO support and GPIO setup features to the S3C processors ...

This patch adds genetic GPIO support to all S3C2440 processor based systems.
Also it adds definitions to setup the pin multiplexer in a way the other
architectures do.

Note: Tested on a S3C2440 based system only. But should work on an S3C2410, too.

Add the basic files for the i.MX23/i.MX28 familiy of CPUs ...

These CPUs are called "i.MX", but they are of type STM378x from SigmaTel. They
do not share any devices with the other i.MX CPUs, so we need a separate
architecute directory to handle them without an ifdef hell in the native i.MX
files.

A9M2440: Use external GPIO settings to setup the SDRAM ...

The generic A9M2440 comes in many SDRAM variantes. Two GPIO pins describing
the populated SDRAM devices. This patch adds some code to query the setting
and setup a correct SDRAM configuration out of four possible variants.

Due to the lack of hardware the 16 MiB and 128 MiB case is untested yet.

Due to the 32 MiB configuration we must link the u-boot-v2 always to
address 0x31fc0000. Even for the 64 MiB and 128 MiB configuration.
