[PATCH 00/22] isa: Resolve unneeded IRQ attributes from ISADevice

[Bernhard Beschow]

The IRQ attributes of ISADevice are hardcoded to support up to two IRQs per
device which creates an artificial limit. By not having the attributes in the
first place, this limitation can be avoided altogether.

The IRQ attributes are mostly used for printing ('info qtree') and there is one
user, hw/ppc/pnv, to use the attributes directly. As it turns out, the printing
is redundant if the IRQ numbers are exposed as QOM properties and hw/ppc/pnv
can be easily ported away.

The patch series is structured as follows: Patch 1-3 QOM'ify the last devices
which rely on printing their IRQ numbers via the ISADevice attributes. Patch
4 and 5 remove the last users of the ISADevice attributes such that they can be
removed in patch 6. The remainder of the patch series is cleanup.

Patch 6 turns isa_init_irq() into a trivial wrapper for isa_get_irq(). That is,
the former function becomes redundant. All users are therefore converted to use
isa_get_irq() directly. Finally, the last patch removes the now unused
isa_init_irq().
