You will need to set the SRCREV for the linux-xlnx-dev package to pick
something other than head of master. You will note that the version
number you see is actually "3.14+-xilinx-dev..." note the '+', this is
just a placeholder value because its not quite so easy to get the
actual version number during the recipe parsing stage.

So if you want the linux-xlnx_3.19 equivalent use commit id
"3f30b3337af61f1ed98f7185e37c6bf9202b3204". And set the SRCREV in your
local.conf like so:

SRCREV_pn-linux-xlnx-dev = "3f30b3337af61f1ed98f7185e37c6bf9202b3204"

Also there is no need to set the PREFERRED_VERSION_linux-xlnx-dev, as
there is only ever one version of the recipe.
