target/arm: Handle NMI in arm_cpu_do_interrupt_aarch64()
According to Arm GIC section 4.6.3 Interrupt superpriority, the interrupt
with superpriority is always IRQ, never FIQ, so the NMI exception trap entry
behave like IRQ. And VINMI(vIRQ with Superpriority) can be raised from the
GIC or come from the hcrx_el2.HCRX_VINMI bit, VFNMI(vFIQ with Superpriority)
come from the hcrx_el2.HCRX_VFNMI bit.
