mailbox: msm_qmp: Remove IRQF_NO_SUSPEND

The qmp interrupt is a hardware wake capable interrupt. Using the
IRQF_NO_SUSPEND flag still allows this interrupt to resume the CPUs
because the interrupt is left unmasked on the gic. Remove this flag
and use enable_irq_wake so the wakeup interrupt is properly accounted
for.
