device-tree: Disable meta-virtualization xen DTSI and apply it only for Linux

In meta-virtualization, when used with meta-xilinx-core, the XEN dtsi was
always enabled, even in a non-Linux based build.  This caused compilation
issues as cortex-r5 and other CPUs are missing required parameters for Xen.
