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.coop...@citrix.com> on lkml message
<5569f9c9.8000...@citrix.com>.
The ifdef for ARM is ugly but did not find better solutions for it.
Then use __kernel_size_t instead of size_t since that is available in
uapi headers in user space.
Fixes userspace compilation errors:
xen/privcmd.h:38:31: fatal error: xen/interface/xen.h: No such file or directory
xen/privcmd.h:92:2: error: unknown type name ‘size_t’
