The rpi-firmware we currently package has a fiscious bug, that happens
in corner cases while reading config.txt (mostly seen on RPi-2, but may
also occur on RPi-1).
Both the DT-aware and DT-unaware branches are affected.
Bump to the latest rpi-firmware to fix that.

Misc fixes and improvements for: DT; hdmi and EDID; video decoding,
latency and cropping; voltage calculations...
Also: support for RPi-2. :-)
Also remove the workaround previously required when installing DTBs, ad
they are now in the same branch as the latest firmware.

Add an option to install all the DTBs:
- standard DTBs for standalon A/B and A+/B+ models;
- overlay DTBs for the 'hats' addon boards.
Install the DTBs as per the traditional layout expected by all RPi
users, that is:
- base DTBs alongside the other boot files;
- overlay DTBs in a sub-directory.
This requires the user provide a specially configured Linux defconfig
file, as the default ones do not enable USE_OF.
[Thomas: adjust comment explaining why we use a different version when
installing the DTBs is selected.]

The Raspberry Pi can boot a kernel with device tree support. But at the
same time, the RPi folks wante to keep the old-fashioned, ATAG-based way
of booting (don't ask...).
So, the bootloader needs to know whether the kernel it is loading has DT
support or not. For that, it looks at the end of the kernel image for a
magic footer. If found, it loads a device tree and sets the registers
appropriately so that the kernel finds the DTB. If not found, it loads
the kernel with the traditional ATAGS.
Where it becomes a bit tricky, is that the DTB is different for models
A/B and A+/B+ (that is A and B use the same DTB, while the A+ and B+ use
a second DTB). The bootloader is capable to load the correct DTB from a
specially named file. That is:
- on A/B, it loads bcm2708-rpi-b.dtb
- on A+/B+, it loads bcm2708-rpi-b-plus.dtb
If the DTB is differently named, the bootloader won't find it, will not
load any DTB at all, and revert to booting with ATAGS.
It is possible to specify what DTB to load, by adding an new config
option 'device_tree=file.dtb' in config.txt, but then the firmware on
the SDcard is no longer bootable on both the original models and the
Plus models.
So, add a script that appends the appropriate footer to the kernel
image. The script is vampirised from the RPi's tools repository, but a
new package is *not* added just for that script: the whole repository is
300+ MiB, and a checkout is 600+ MiB; it is not pertinent to add this as
a new package for a script that weights a few KiB...
Install that script as a host utility, too.
Notes: lots of information is available in this thread on the RPi forums:

Of utmost importance, this bump allows to overclock the RPi to even
higher frequencies: ARM > 1200MHz, core > 600MHz, RAM > 600MHz. :-)
To be used with caution, of course! :-)
Fixes and enhancements for:
- clocks : allow higher overclocks
- audio : PCM channel expansion/conversion
- video : stutter on streams without b-frames, choice of scaling /kernel/
- camera : padding-removal, new YUV and BGR modes
- decoder: timestamps fixes, frames interval tracking
- encoder: misc jpeg encoding fixes, save inline motion vectors
- display: don't require EDID on HDMI

Updating brings in a new bootloader that enables more free codecs:
MJPEG, VP6, VP8, Ogg Theora and Ogg Vorbis
Also, the command-line definition has moved to its own file, now.
Although the legacy 'cmdline' variable seems to still be supported
for a little while, better switch now than forget when we upgrade
later.

The default name of the kernel binary for the RaspberryPi is kernel.img,
it's only a zImage kernel renamed. Since Buildroot will build a zImage, the
default config should use the zImage name instead of forcing the user to
rename a file.
This patch also remove the cmdline argument rootfstype. There is no point
forcing the user to use ext4 for its root partition.
