Given Minnowboard and Minnowboard MAX boards are very similar,
it's desirable to unify the support for them.
This commit does the following:
1) Remove Minnowboard MAX's genimage.cfg, post-build.sh
and post-image.sh. These are identical to Minnowboard's.
2) Move Minnowboard MAX's linux config, and rename it.
It would be lovely to have a single kernel config file.
The kernel size penalty involved in adding support for
all the peripherals on both boards is small enough to
justify this.
However, the original Minnowboard has some GPIO buttons
that need to be registered by the kernel. This is not
upstreamed, and hence we need to use the yocto v3.8 kernel
to have this support.
3) Rename each grub config to grub-{board}.cfg.
4) Modify (the now unique) post-build script to use
a different grub config, according to the board.
5) Update both defconfigs, as per the above changes.
6) Finally, update the readme.txt.

Let's rework the board and config files to use genimage
to generate the SD card image directly.

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.
