Add isa_reserve_irq().
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...
Move isa_connect_irq calls into isa_create_simple

Hi,
