xive/p10:: Declare xive2 DT node as an interrupt-controller
This patch fixes errors seen when linux looks for the interrupt to use
for a device LSI:
pci X:Y:Z of_irq_parse_pci: failed with rc=-22
The of/irq parsing code requires those new properties to be able to
map the interrupt specifier correctly. It was not needed before
comitting cd12ea6d8e1 ("interrupts: Do not advertise XICS support on
P10"), because the LSI mapping code was defaulting to the XICS
interrupt controller node, which is now removed (and had those
properties).
Fixes: cd12ea6d8e1 ("interrupts: Do not advertise XICS support on P10")
