In the RFC e-mail change regarding README.imx6-something,
I proposed that we replace the pad declaration form
currently in use:

enum {
	MX6_PAD_SD3_DAT2__USDHC3_DAT2 = IOMUX_PAD(...)
};

with macros of this form so that they can be pre-pended
with MX6Q_ and MX6DL_ when we need both in an image
(SPL?) that can run on either variant of processor.

	MX6_PAD_DECL(SD3_DAT2__USDHC3_DAT2, ...)

If we do this, then lining up the columns based on the
first form doesn't make much sense.

Section 3 of this post is the easiest place to see things:

This post has my list of oustanding questions:

	http://lists.denx.de/pipermail/u-boot/2013-November/166876.html

And we're addressing #1 and 2:
	1. Whether to turn declarations in mx6q_pins.h/mx6dl_pins.h
	into macros
	2. Whether to double-include the same in mx6-pins.h
	3. Whether to define baseline pads (the 90% case) in a header
	and double-include it, and
	4. Whether to macro-fy the memory layout files like
	1066mhz_4x128mx16.cfg so they can be used by imximage and gcc.
