[PATCH 2/3] xen: simplify xen_enabled

[Stefano Stabellini <stefano.stabellini@eu.citrix.com>]

No need for preprocessor conditionals in xen_enabled: xen_allowed is
always defined.

Please backport this patch to stable branches (it is needed by the
following patch to remove the dependency on a preprocessor identifier
defined by config-target.h).
