ANDROID: Enable CONFIG_ARM64_PSEUDO_NMI 



The CONFIG_ARM64_PSEUDO_NMI configuration macro needs to be enabled. Pseudo NMI has many benefits:
(1) It solves the problem of sensitive interrupts being delayed due to lock interrupts, significantly reducing the response delay of sensitive interrupts
(2) It can help locate hard lockup problems caused by interrupt masking
(3) Through IPI_CPU_STOP_NMI, it can also detect CPU stop failures caused by interrupt masking

There is no disadvantage, because if the user does not want to use the pseudo NMI function, the default setting of irqchip.gicv3_pseudo_nmi is disabled.
