Introduce isa_reserve_irq() which marks an irq reserved and returnsthe appropriate qemu_irq entry from the i8259 table.
isa_reserve_irq() is a temporary interface to be used to allocate ISAIRQs for devices which have not yet been converted to qdev, and for...

isa bus irq changes and fixes.

qdev/prop: convert isa-bus to helper macros.
qdev/isa: add isa bus support to qdev.
Pretty simple and straigt forward.IRQs modeled simliar to sysbus.
