This commit introduces a new arm-specific flag CDF_directmap to specify
that a domain should have its memory direct-map(guest physical address
== host physical address) at domain creation.
Also, add a directmap flag under struct arch_domain and use it to
reimplement is_domain_direct_mapped.
For now, direct-map is only available when statically allocated memory is
used for the domain, that is, "xen,static-mem" must be also defined in the
domain configuration.
