xen: select grant interface version ...
Grant v2 will be needed in cases where a frame number in the grant
table can exceed 32 bits. For PV guests this is a host feature, while
for HVM guests this is a guest feature.
So select grant v2 in case frame numbers can be larger than 32 bits
and grant v1 else.
For testing purposes add a way to specify the grant interface version
via a boot parameter.
