configs: add a DT-enabled Raspberry Pi defconfig
This is an example of a Device-Tree-enabled Raspberry Pi defconfig.
We have to use a 3.18-based kernel for that, but there are a few
limitations:
- we can not use the minimalist RPi defconfig bundled with the kernel,
namely bcmrpi_quick_defconfig, because it is not DT-enabled, and
sets CONFIG_ARM_PATCH_PHYS_VIRT to 'n', which prompts a value for
CONFIG_PHYS_OFFSET, as it as no default for the bcm familly;
- most importantly, the rpi-3.18.y branch is constantly rebased, so
there is no guarantee that the sha1 I use today will still be usable
in the long term. Using the name of hte branch is not better either.
So, we bundle our own DT-enabled linux defconfig that is based on
bcmrpi_quick_defconfig, with just CONFIG_ARM_PATCH_PHYS_VIRT set and the
Device TRee enabled.

configs: switch to a wget download for kernels on github
The linux git trees on github can be huge, and takes a long time to
download, which is not very nice nor convenient for newcomers.
Switch them to using a wget, with the github macro.
A nice side effect of this conversion, is that we no longer need to wait
for the git clone to finish to notice that the ref is gone; doing a wget
will instantly fail in that case.
Mechanical patch, obtained by running (hang-on tight):
$ sed -r -i -e 's/BR2_LINUX_KERNEL_CUSTOM_GIT/BR2_LINUX_KERNEL_CUSTOM_TARBALL/; /BR2_LINUX_KERNEL_CUSTOM_REPO_URL/N; s:BR2_LINUX_KERNEL_CUSTOM_REPO_URL="https\://github.com/([^/]+)/(.+)"\nBR2_LINUX_KERNEL_CUSTOM_REPO_VERSION="(.+)":BR2_LINUX_KERNEL_CUSTOM_TARBALL_LOCATION="$(call github,\1,\2,\3)/linux-\3.tar.gz":; s/(call github.*)\.git/\1/;' $(grep -l 'BR2_LINUX_KERNEL_CUSTOM_REPO_URL="https://github.com' configs/*)
olimex_a20_olinuxino_lime_mali had a comment in between, so it was
manually fixed thereafter; that comment was also moved.
Except for socrates_cyclone5 which did not work previously (missing tag
in git tree?), all the affected defconfigs still download their sources.
