xen: use a common function for pv and hvm guest backend register calls

Browse source 
Instead of calling xen_be_register() for each supported backend type
for hvm and pv guests in their machine init functions use a common
function in order not to have to add new backends twice.

This at once fixes the error that hvm domains couldn't use the qusb
backend.
