[RFC PATCH v5 19/22] hw/intc/arm_gicv3: Report the NMI interrupt in gicv3_cpuif_update()

[Jinjie Ruan]

In CPU Interface, if the IRQ has the superpriority property, report
NMI to the corresponding PE.

Signed-off-by: Jinjie Ruan <ruanjinjie@huawei.com>

v4:
- Swap the ordering of the IFs.
v3:
- Remove handling nmi_is_irq flag.
