[Qemu-devel] [RFC PATCH v5 12/14] irq: Add opaque setter routine

[Peter Crosthwaite]

Add a routine to set or override the opaque data of an IRQ.

Qdev currently always initialises IRQ opaque as the device itself.
This allows you to override to a custom opaque in the case where
there is extra or different data needed.
