corstone700: fdts: using DDR memory and XIP rootfs 

This patch allows to use DDR address in memory node because on FPGA we
typically use DDR instead of shared RAM.

This patch also modifies the kernel arguments to allow the rootfs to be
mounted from a direct mapping of the QSPI NOR flash using the physmap
driver in the kernel. This allows to support CRAMFS XIP.
