[PATCH v05 54/72] include/uapi/xen/privcmd.h: fix compilation in userspace

xen/interface/xen.h is not exported from kernel headers so remove the
dependency and provide needed defines for domid_t and xen_pfn_t if they
are not already defined by some other e.g. Xen specific headers.
Suggested by Andrew Cooper <andrew.cooper3 at citrix.com> on lkml message
<5569F9C9.8000607 at citrix.com>.
The ifdef for ARM is ugly but did not find better solutions for it.
Fixes userspace compilation error:
xen/privcmd.h:38:31: fatal error: xen/interface/xen.h: No such file or directory
