[Qemu-devel] [PATCH v4 02/26] ppc/xics: fix ICP and ICS reset

["Cédric Le Goater" <clg@kaod.org>]

commit 5b17c7207938 ("xics: XICS should not be a SysBusDevice")
changed the nature of the XICS object to be a descendent of
TYPE_DEVICE. By doing so, the object is not on a bus and its reset
handler is not called anymore. The direct consequence is that the ICP
and ICS objects are not correctly initialized and so the IRQ subsystem
is broken in the guest.
