Add acpi_arch_get_root_pointer() for Xen PVH guests to communicate the address of the RSDP table given to the kernel via Xen start info. This makes the kernel boot again in PVH mode after on recent Xen the RSDP was moved to higher addresses. So up to that change it was pure luck that the legacy method to locate the RSDP was working when running as PVH mode.
