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.

The genimage configuration creates a vfat filesystem, so ensure we have
dosfstools / mtools built for the host.

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.

This patch updates the Cubieboard2 board defconfig to use newer u-boot
and linux versions, along with a few other improvements.
The other improvements were mostly backported from the recent Orange Pi
defconfig inclusion and are related to image generation.
linux-sunxi.org was used as a reference for both linux and u-boot
defconfig names.
In detail:
- Update linux to vanilla upstream -- currently 4.3.3 is the most
up-to-date. Although it lacks some features present only in the
linux-sunxi 3.4 branch, upstream support appears to be relatively mature
and is already being deployed by default by distributions such as Arch
Linux ARM.
- Update u-boot to vanilla upstream 2015.10. According to
linux-sunxi.org, upstream fully supports major functions (except NAND)
since 2015.07.
- Change image format to zImage and drop custom image generation script
in favour of genimage, as pointed out by reviewers in the Orange Pi
defconfig submission.
This was tested in a Cubieboard2 board with boot from mmc and it boots
fine to login prompt.
This has not been tested in a Cubieboard (A10) as I don't own any; the
version bumps probably apply to it although there are some differences
(lack of VFPv4 support, Cortex-A8 instead of Cortex-A7), so I have kept
the current Cubieboard defconfig and its scripts. This one has been only
build-tested.
