x86/xen: Drop xen_irq_ops

Browse source 
Instead of having a pre-filled array xen_irq_ops for Xen PV paravirt
functions, drop the array and assign each element individually.

This is in preparation of reducing the paravirt include hell by
splitting paravirt.h into multiple more fine grained header files,
which will in turn require to split up the pv_ops vector as well.
Dropping the pre-filled array makes life easier for objtool to
detect missing initializers in multiple pv_ops_ arrays.
