u-boot-zynq-scr:Add initrd label to pxe config

This patch adds the initrd label command to pxe config file
which is required to boot linux in pxeboot with initrd image.

initrd <path> - if this label is chosen, use tftp to retrieve the initrd
		at <path>. it will be stored at the address indicated in
		the initrd_addr_r environment variable, and that address
		will be passed to bootm
