This requires some changes to KERNEL_DEVICETREE as the dtb
layout has changed to support overlays. This change also
makes us ready to support kernel 4.x series

The kernel debugger over console (kgdboc) parameter is being added
unconditionally to the kernel command line but this means that the
kernel will stop and wait for gdb to attach in case of a exception
or when sending a sysrq-g key. This behaviour may not be what most
users wants that are not remotely debugging the kernel over serial
console so make it optional by adding a ENABLE_KGDB config option.

After '6392a63 rpi-base.inc: Use KERNEL_DEVICETREE by default' was
introduced, kernel versions < 3.18 might not be buildable. Since full
device tree support was introduced in 3.18 this change ensures that all
kernel < 3.18 will automatically disable device tree.

Add basic support for Linux 3.14, cherry-pick changes from 3.18.y in
order to solve some debugfs warnings and get better support
for i2s for BCM2708.
- 3.14 lacks BCM2709 support and will not by default be able to use for
raspberry pi 2.
Below warnings still exists they are harmless and exists due to that
snd_soc_pcm512x is triggered to be loaded twice. The problem is solved
after device tree support for the driver was introduced in 3.18.y and no
easy solution exists to solve this problem on older kernel versions (see
https://github.com/raspberrypi/linux/issues/662 for more info).

We use this to simplify the update process. Updating a kernel version will not
require renaming the recipe but only tweaking LINUX_VERSION.
Update kernel version:
- bump SRCREV
- bump LINUX_VERSION if needed

[RPi DT info] https://github.com/raspberrypi/documentation/blob/master/configuration/device-tree.md#part-3-using-device-trees-on-raspberry-pi
RPi bootloader detects a DT-ready kernel by checking for a specific trailer in kernel.img.
Using latest raspberrypi/firmware (firmware.inc) enables this check ability.
Using latest raspberrypi/tools (rpi-mkimage.bb) gives access to mkknlimg for adding the
required trailer to kernel image.
If KERNEL_DEVICETREE is filled in, the trailer is added to the kernel image before
kernel install task. While creating the SDCard image, this modified kernel is
put on boot partition (as kernel.img) as well as DeviceTree blobs (.dtb files).
If KERNEL_DEVICETREE is empty, this new process isn't operated, legacy one does.
KERNEL_DEVICETREE for RPi is really supported only starting from linux-rapsberry 3.18+
kernels, so as for now it defaults to empty (in machine config file).

Yocto style recipes provide support for application of kernel
configuration fragments which is achieved with this change.
For further details see the Yocto Linux Kernel Development Manual
ref: http://www.yoctoproject.org/docs/1.6/kernel-dev/kernel-dev.html
In addition .bb files are simplified to take a SRCBRANCH which is
used by the SRC_URI set in linux-raspberrypi.inc and together with
the existing SRCREV define a checkout from the linux-raspberrypi
git repository.
A default configuration, defconfig, is provided as a baseline.
This is generated from bcmrpi_defconfig, as used in the existing
recipes, and so configuration options should be the same.
To change the kernel configuration a new configuration fragment
may be generated, as explained in the kernel development documentation
above, and this file then added to the SRC_URI via a .bbappend.
Added some minor refactoring and removed some useless code.

Amongst other patches, this release includes a fix to an issue with
gstreamer1.0 and v4l2src blocking
ref: https://bugzilla.gnome.org/show_bug.cgi?id=726521
ref: http://tinyurl.com/mkqooeg
To make use of the optional fix the module parameter gst_v4l2src_is_broken
needs to be set when loading bcm2835-v4l2.ko
With this in place, and with userland and gstreamer1.0-omx patches,
gstreamer1.0 can be used with PiCam via v4l2src instead of raspivid.
(There may still be performance issues to be addressed for v4l2src vs
raspivid pipe & fdsrc).
