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.

This enables Vpp and disables the flash protection on the
Integrator when starting U-Boot. The integrator/AP has double
protection mechanisms: this one and the EBI protection bit
(patch earlier), the Integrator/CP has only one line of
protection in these registers.

Break out the AP system controller and CP "CP controller"
registers into a header file, it gives better overview than
hardcoding its values and other disturbing practices.

This reconfigures the EBI (External Bus Interface) on the
integrator so that chip select 1, handling the flash memory, is
set to writeable. Without this it is not possible for U-Boot to
access flash memory and it crashes on startup since CFI won't
work properly.
Since this is the first time we use the EBI, we create a header
file for its registers.

Casting around to *(volatile ulong *) doesn't look good, so include
the <asm/io.h> macros and use good old readl() instead.

When booting from Flash, the Integrator remaps its flash memory
from 0x24000000 to 0x00000000, and starts executing it at
0x00000000. This ROM thus hides the RAM underneath and first
0x40000 bytes of the memory cannot be tested by get_ram_size().
So let's test from 0x40000 to the end of detected memory
instead.
