irq: Allocate IRQs individually
Allocate each IRQ individually on array allocations. This prepares for
QOMification of IRQs, where pointers to individual IRQs may be taken
and handed around for usage as QOM Links. The g_renew() scheme used here
is too fragile and would break all existing links should an IRQ list
be extended.
We now have to pass the IRQ count to qemu_free_irqs(). We have so few
call sites however, so this change is reasonably trivial.
