Also adding the '-m4' device tree blobs which allow to disable the
peripherals that are used by the Cortex-M4.
The 6x_bootscript is already setup to load the '-m4' dtb if m4enabled
u-boot variable is set to 1.

Since quite some time, the kernel and bootloader communities consider
zImage as the default format for kernel images on ARM, replacing
uImage. The load address information in uImage is no longer needed,
since the kernel is position-independent in terms of physical address,
except on a few old platforms. For most people, using zImage is simply
better/simpler, so let's switch to zImage as the default image format
on ARM.
All defconfigs are updated: 46 defconfigs no longer need to select
explicitly zImage because it's the default, and 16 defconfigs now need
to explicitly select uImage because that's no longer the default.

It didn't make sense to keep the U-Boot scripts and post build/image
scripts under the nitrogen6x folder since they apply for all our
platforms.
Also update the readme.txt to make it clearer which defconfig should
be used depending on the platform targeted.

This board is using a different kernel and u-boot branch than the
other Boundary Devices platforms since NXP forked the 3.14 kernel to add
i.MX7 support (see imx_3.14.38_6ul7d_beta branch).
Next kernel version, 3.14.52, will be the same for all i.MX platforms.
