On the MX27 based board phycard-i.MX27 the display won't properly
come up.
Before removing imx-regs.h and the code that sets the register
in the i.MX video driver, the PCCR registers were set _after_
the screen start (LSSAR) was set.
This restores that old behaviour and makes the display come up
properly again.
I did not have a chance to test this on any other i.MX27 or i.MX21
hardware though I assume that the "old" order is required there
too.

The i.MX27/31 have the second chip select enabled by reset default.
This can be considered as a hardware bug, because even boards which

This adds support for an update handler for internal boot. Currently
handled are:
- v1 MMC/SD
- v2 MMC/SD
- v2 NAND
where v1 is found on i.MX25, i.MX35 and i.MX51. v2 is found on i.MX53.
This code intentionally does not use the DCD data compiled into every
i.MX internal boot image. This makes it possible to make a pure second
