* [PATCH] xen: move xen_sysdev to xen_backend.c

Commit 9432e53a5bc88681b2d3aec4dac9db07c5476d1b added xen_sysdev as a
system device to serve as an anchor for removable virtual buses. This
introduced a build failure for non-x86 builds with CONFIG_XEN_BACKEND
set, as xen_sysdev was defined in a x86 specific file while being
consumed in an architecture independent source.

Move the xen_sysdev definition and initialization to xen_backend.c to
avoid the build failure.
