[Buildroot] [pull request] raspberrypi: update packages and defconfigs

[Yann E. MORIN <yann.morin.1998@free.fr>]

Hello All!

This series updates our support for the RaspberryPi line of boards:
RaspberryPi models A and B, A+ and B+, and model 2 B.

Patch 1 reinstates the Kconfig knob to install the DTBs, as the ones
from rpi-firmware are kernel-version specific, and can't be used with
kernels >= 3.19 (boot hangs because no root device found).

Patch 2 adds an option to intall the DTB overlays. They are bundled in
source form in thre kernel tree, but Buildroot lacks the infra to build
DT overlays in the kernel, so we install them from rpi-firmware.

Patch 3 adds the option to install a utility to diagnmose issues when
talking to the GPU (useful to debug DT-related issues... when booted!)

Patches 4-5 update our rpi-firmware and rpi-userland packages. Nothing
tremenduously interesting, though, except the usual fixes and small
improvement for new hardware support.

Patches 6-10 update our defconfig files and drops the defconfig without
DT support.

Patch 11 update the board instructions.

Thanks to Floris and Pascal for their initial works! :-)

Regards,
Yann E. MORIN.
