Roger Pau Monné 69138e8788 xen/intr: improve handling of legacy IRQs
Devices that use ISA IRQs expect them to be already configured, and don't
call bus_config_intr, which prevents those IRQs from working on Xen. In
order to solve it pre-register all the legacy IRQs with the default values
(edge triggered, low polarity) if no override is found.

While there add a panic if the registration of an interrupt override fails.
