linux-cubox-i: upgrade to 3.14.14 version

This is the new SolidRun supported kernel for the HummingBoard and
CuBox-i devices. It is based on the Linaro 3.14 kernel releases.

Some of the changes are:

* devicetree files are used now
* zImage is used instead of uImage
* large amounts of memory leak and stability fixes
* increased FEC ethernet performance, higher than the Freescale rated
  470 Mbps
* SDHC patchset for better UHS-I support
* residue support for SDMA with FSL's custom firmware integrated to work
  with HDMI and optical SPDIF
* higher DMA and GPU efficiency in general
* the vast array of improvements of a 3.14.14 kernel over a 3.0.35 one
