Align the SSP clock speed with oscilator to achieve
higher transfer stability.

The DRAM initialization, after SPL has complete, is exactly the same
for all mxs SoCs so we should name it accordinly.
The following boards has been changed:
* apx4devkit
* m28evk
* mx28evk
* sc_sps_1

This prototype version SoM is unused and not available to public.
Support this only for internal debugging purposes.

Remove 'all' target from Makefile, as this is unused code.

Let dram_init function be a common function, so that other mx28 boards
can reuse it.

Add multi-FEC support for imx_get_mac_from_fuse by passing dev_id as a parameter.
This feature is important on mx28 SoC for example that has two FEC ports.

This moves SPL to common location so it can be reused by multiple boards. Also,
this commit adjusts M28 SoM to avoid breakage due to the move.

This enables the second port, aka. the port with the USB connector on the
M28EVK.

This code allows the DDR DRAM size to be detected at runtime. The RAM size is
stored into two scratch registers, from which it is then fetched in U-Boot.

This patch introduces proper ARM vector handling for i.MX28 CPU. This issue
wasn't addressed because the interrupts weren't enabled on any ARMv5 core,
therefore the issue wasn't noticed earlier.
In previous implementation, the vectoring code used by i.MX28 CPU when an
exception happened was that of the SPL. With this change, the branch target when
an exception happens can be reconfigured by U-Boot.
