Check for a node in the device tree compatible with "xen,xen", if it is
present set xen_domain_type to XEN_HVM_DOMAIN and continue
initialization.
Map the real shared info page using XENMEM_add_to_physmap with
XENMAPSPACE_shared_info.
Changes in v4:
- simpler parsing of Xen version in the compatible DT node.
Changes in v3:
- use the "xen,xen" notation rather than "arm,xen";
- add an additional check on the presence of the Xen version.
Changes in v2:
- replace pr_info with pr_debug.

- Basic hypervisor.h and interface.h definitions.
- Skeleton enlighten.c, set xen_start_info to an empty struct.
- Make xen_initial_domain dependent on the SIF_PRIVILIGED_BIT.
The new code only compiles when CONFIG_XEN is set, that is going to be
added to arch/arm/Kconfig in patch #11 "xen/arm: introduce CONFIG_XEN on
ARM".
Changes in v3:
- improve comments.
