linux-raspberrypi: Update 3.12 branch to latest

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.

[Support #60]
