fastboot: Add a ARM Barebox filetype handler ...

This will automatically call barebox_update for the transfered file if
it is an ARM Barebox image and the destination file is defined by some
update handler.

bootm: Fix booting uImages ...

This fixes:
0a37e22d (bootm: use names instead of numbers for image parts)

This commit switches to strings for the image numbers for better FIT
image support (which uses names instead of numbers). These strings
may be NULL when no image number is given. They are used uninitialzed
in several places. Introduce a wrapper function to convert the string
into a number. Check for NULL here in which case we return 0 which
is the correct value.

Print error message if of_state_fixup() fails ...

If of_state_fixup() fails for some reason, boot/bootm will fail, too

However, it is completely unclear where the error has happened, and to
the user it rather seems like the kernel device tree loaded from some
file was broken/corrupt, not that in fact some fixup routine was
failing.

Adding a meaningful error message can help debugging significantly.

bootm: Add option to force booting signed images ...

With CONFIG_BOOTM_FORCE_SIGNED_IMAGES the bootm code will refuse to boot
unsigned images. Since currently FIT is the only image type which
supports signing, this means with this option we enforce using FIT
images. All additionally passed in device trees and initrds will be
ignored, so that only the ones from the FIT image can be used.

bootm: add initial FIT support ...

This implementation is inspired by U-Boot's FIT support. Instead of
using libfdt (which does not exist in barebox), configuration signatures
are verified by using a simplified DT parser based on barebox's own
code.

Currently, only signed configurations with hashed images are supported,
as the other variants are less useful for verified boot. Compatible FIT
images can be created using U-Boot's mkimage tool.
