From: Rob Herring <rob.herring at calxeda.com>
xen_pm_init was unconditionally setting pm_power_off and arm_pm_restart
function pointers. This breaks multi-platform kernels. Move this
initialization into xen_guest_init, so it is conditional on running as a
Xen guest.

This breaks reset and poweroff for Midway when Xen is enabled. This
should go into 3.11 or stable.
