Add a new config option PARAVIRT_XXL which is selected by XEN_PV. Later we can put the Xen PV only paravirt ops under the PARAVIRT_XXL umbrella. Since irq related paravirt ops are used only by VSMP and Xen PV, let VSMP select PARAVIRT_XXL, too, in order to enable moving the irq ops under PARAVIRT_XXL.
