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.

Since commit 2a5cf5e (check kernel headers version), we also need to
specify the series of the custom kernel headers version.
The defconfigs file that define such a custom kernel headers version
now fail to build.
Add the required _AT_LEAST_X_Y options to those config files. Done with
this (convoluted but very fast, uch faster ythan manual editing!) rule:
for f in $( git grep -l BR2_DEFAULT_KERNEL_VERSION=\"3 ); do
grep -E '^BR2_PACKAGE_HOST_LINUX_HEADERS_CUSTOM_' "${f}" >/dev/null && continue
sed -r -e '/^(BR2_DEFAULT_KERNEL_VERSION="3\.([[:digit:]]+).*")$/s//\1\nBR2_PACKAGE_HOST_LINUX_HEADERS_CUSTOM_3_\2=y/' "${f}"
done
Only kernels >= 3.0 need those options in the defconfig, since the
default for 2.6.x kernels is correct (selects _AT_LEAST_2_6), and
the default is not saved in a defconfig.
