[meta-xilinx] [PATCH 01/12] device-tree.bb: Add support to use kernel source tree includes

[Nathan Rossi]

* Add support to use the base platform includes directly from the
  currently selected kernel source tree
* Setup 'zynq-7000.dtsi' as default for 'zynq' targets
* Setup 'zynqmp.dtsi' as default for 'zynqmp' targets
* Remove use of awk, use basename -s instead
