scripts/runqemu: Add support for 'qemuzynq' machine

Browse Source 
* Add support to boot the 'qemuzynq' machine in qemu-system-arm
* Use the specific machine model for Zynq 'xilinx-zynq-a9'
* Use the DTB generated from the kernel build as the DTB for boot
* Force use of initrd rootfs (either in ext or cpio formats)
