[RFC PATCH v9 07/23] target/arm: Add support for NMI in arm_phys_excp_target_el()

[Jinjie Ruan via <qemu-devel@nongnu.org>]

According to Arm GIC section 4.6.3 Interrupt superpriority, the interrupt
with superpriority is always IRQ, never FIQ, so handle NMI same as IRQ in
arm_phys_excp_target_el().
