External NOR boot only requires copying the image to NOR Flash.
This also adds (un)protecting the flash which is required for
NOR Flash.

The i.MX barebox update handlers take an optional dcd table as argument.
This can be used to add the correct dcd data to the image before flashing
it.
This mechanism is quite complicated and largely unused, so remove it. With
this it is only possible to flash the exact image passed to barebox_update,
which is what is mostly done anyway.

A lot of files rely on include/driver.h including include/of.h (and
this including include/errno.h. include the files explicitly so we can
eventually get rid of including of.h from driver.h

The external NAND boot code currently does not handle bad blocks
correctly on 2k NAND flashes. This patch adds a barebox_update
handler for external NAND boot which embeds a Bad block table in
the flashed image. The boot code will skip bad blocks found in
this bad block table then.

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
stage barebox bootable on i.MX internal boot devices later.
This has been tested on the i.MX51 babbage, i.MX53 loco and i.MX53 tx53
board.
