imxtools: completely rework patching logic to prepare unpatching
The old code was working but a mess to maintain. The new code is cleaner
and always simpler handling of all the different options. Extraction of the
OF is no longer a standalone function but just one particular output type.
This commit prepares the ground for firmware "unpatching" (aka OF extraction
from patched OF). The patching code itself did not change so this commit
should still produce the exact same images as before.
