[meta-xilinx] Kernel version, xilinx git repo, yocto kernel

[Mike Looijmans]

Simple solution would be to just stop using the cadence driver. There are 
issues in the Zynq that cannot really be resolved in software apparently, and 
the only way around them we've found is to just use a bitbang GPIO controller 
on the same pins. That made all problems go away.

Chances are that moving to a newer kernel will not resolve your I2C issues anyway.
