Update linux-raspberrypi_3.12 to latest revision.
Remove sl030raspberrypii2ckernel.patch since it will not apply anymore
and its content seems to be obsolite after
'558d0bf Fix grabbing lock from atomic context in i2c driver' was
merged to 3.12.

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).

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.

When building against newer yocto project releases below failure
occurs.
| DEBUG: Executing shell function do_configure
| NOTE: make oldconfig
| make: *** No rule to make target `oldconfig'. Stop.
| ERROR: oe_runmake failed
| WARNING: exit code 1 from a shell command.
| ERROR: Function failed: do_configure
Fix this by trying to adapt more of the standard mechanism
that exists in yocto, in order to build "custom kernels".

I was having intermittent i2c issues on the device until I applied this kernel patch
which I found online.
