MIPS: Loongson-3: Add IRQF_NO_SUSPEND to Cascade irqaction

commit 0add9c2f upstream.

HPET irq is routed to i8259 and then to MIPS CPU irq (cascade). After
commit a3e6c1ef (MIPS: IRQ: Fix disable_irq on CPU IRQs), if without
IRQF_NO_SUSPEND in cascade_irqaction, HPET interrupts will lost during
suspend. The result is machine cannot be waken up.
