Done and submitted for MX51 - and Efika MX is ported and through QA.
Can you review?

Benoit has some valid suggestions for changes, which can come later,
but for now moving to that for MX51 boards should be a net zero
difference for all implemented boards. I don't have space on my desk
to fire up my MX53 Quickstart or EVK to test those, but porting the
files for MX53 from Linux should not be a big deal and further
combining the 3 implementations differences (moving GPIO_NUMBER to
imx-common/iomux-v3.h instead of it being SoC-specific for example) is
something that would better be done once everything's in and working.
