mailbox: msm_qmp: remove IRQF_NO_SUSPEND while requesting irq



Using IRQF_NO_SUSPEND and enable_irq_wake together can sometime
cause issue in wakeup from suspend and local host may not come
out of suspend on receiving qmp interrupt.

It is sufficient to use enable_irq_wake to mark irq as wakeup
capable.
