meta-xilinx-bsp:uboot-device-tree: provencore memory reservation

Provencore Linux driver and testapp is enabled through MACHINE_FEATURES.
When provencore is enabled, reserve memory required for provencore through
uboot device tree.
This patch adds pnc.dtsi to system-top.dts file when provencore is enabled.
pnc.dtsi contains the memory address and memory size that needs to be reserved.
