[PATCH 04/10] ARM: imx_v6_v7_defconfig: cleanup mxs_defconfig

[Dario Binacchi]

Generate imx_v6_v7_defconfig by doing:

make imx_v6_v7_defconfig
make savedefconfig
cp defconfig arch/arm/configs/imx_v6_v7_defconfig

No functional change. The goal here is to cleanup imx_v6_v7_defconfig
file to make easier and cleaner the addition of new entries.

00:04:9f is Freescale Semiconductor. Since you are not Freescale, are
you actually allowed to use this MAC address?

If you look around, you find most boards use 00 00 00 00 00 00 as a
place holder, and the bootloader puts in the real per device MAC
address.

we usually put iomuxc at the end of the file.

For the dts files, I replied with a few with my R-b, but I just realize that
need put iomuxc at end of the dts file, so please address those, then
you could keep my R-b.
