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.

For most defconfigs, it was trivial to deduce the kernel version, by
just reading the version string, which could be:
- a standard upstream version string vX.Y.Z
- a non-standard version string, but still containg the standard X.Y.Z
Those for which it was not so trivial were those hosted on git tree.
Since most were already using a custom linux-headers version, it could
be easily deduced from that. It was confirmed by browsing said git trees
and check the version there.
There are a few cases were there was a mismatch:
- microzed: uses a 3.18 kernel, but 3.8 headers; fixed.
- xilinx_zc706: uses a 3.14 kernel, but 3.8 headers; fixed.
- zedboard: uses a 3.18 kernel, but 3.8 headers; fixed.

Rename imx6sabresd board folder to imx6sabre, to prepare for Sabre Auto
addition. Update doc, link and defconfigs accordingly.

The current defconfigs for iMX6 SABRESD kernel 3.10.17 from the Freescale
git repository. This kernel is older than the toolchain kernel headers
used in Buildroot (currently 3.16.3).
Explicitly lock down the kernel headers to match the version of the kernel
that is built.

The best practice is to use the BR2_GLOBAL_PATCH_DIR for patches against

Buildroot supplies a nice /init wrapper script to use when booting from a
ramdisk.
We add a patch to u-boot to tell the kernel to boot into /init (instead of
/linuxrc) on i.MX6, when booting in mfgtools mode. This way we can boot a
buildroot system entirely through USB.

This is very similar to freescale_imx6qsabresd_defconfig, which supports the
i.MX6Q ("Quad", quad core CPU) version of the board, except it supports the
i.MX6DL (DualLite, dual core CPU) version.
The differences are in the U-boot configuration and the device tree file.
