hv: pirq: add static irq:vector mappings

Browse Source 
Since vector is x86 specific concept, we'd like to hide it from common irq APIs.
This commit
 - adds static irq:vector mappings for special interrupt such as timer
and cpu notification;
 - reserves the irq and vector at initialization;
 - removed the vector argument in pri_register_handler(), get reserved vector
   from irq_desc in common_register_handler().
