INTRNG: Rework handling with resources. Partially revert r301453.

 - Read interrupt properties at bus enumeration time and store
   it into global mapping table.
 - At bus_activate_resource() time, given mapping entry is resolved and
   connected to real interrupt source. A copy of mapping entry is attached
   to given resource.
 - At bus_setup_intr() time, mapping entry stored in resource is used
   for delivery of requested interrupt configuration.
 - For MSI/MSIX interrupts, mapping entry is created within
   pci_alloc_msi()/pci_alloc_msix() call.
 - For legacy PCI interrupts, mapping entry must be created within
   pcib_route_interrupt() by pcib driver itself.
