xen_arm: Initialize RAM and add hi/low memory regions
In order to use virtio backends we need to initialize RAM for the
xen-mapcache (which is responsible for mapping guest memory using foreign
mapping) to work. Calculate and add hi/low memory regions based on
machine->ram_size.
Use the constants defined in public header arch-arm.h to be aligned with the xen
toolstack.
While using this machine, the toolstack should then pass real ram_size using
"-m" arg. If "-m" is not given, create a QEMU machine without IOREQ and other
emulated devices like TPM and VIRTIO. This is done to keep this QEMU machine
usable for /etc/init.d/xencommons.
