xen/arm: GICv3: Only initialize ITS when the distributor supports LPIs.

There are firmware tables out describing the ITS but does not support
LPIs. This will result to a data abort when trying to initialize ITS.

While this can be consider a bug in the Device-Tree, same configuration
boots on Linux. So gate the ITS initialization with the support of LPIs
in the distributor.
