#     powerpc/pci: unmap all interrupts when a PHB is removed
#     
#     Some PCI adapters, like GPUs, use the "interrupt-map" property to
#     describe interrupt mappings other than the legacy INTx interrupts.
#     There can be more than 4 mappings.
#     
#     To clear all interrupts when a PHB is removed, we need to increase the
#     'irq_map' array in which mappings are recorded. Compute the number of
#     interrupt mappings from the "interrupt-map" property and allocate a
#     bigger 'irq_map' array.
