[oe] [meta-xilinx] xilinx-kernel: Change string comparision checks to use strict POSIX compliance.

[Elvis Dowson]

This commit fixes an issue with string comparision checks failing because
of not using strict POSIX compliance, therby failing to copy the device
tree from the hardware model to the linux kernel device tree.
