The MSM GPIO IRQ controller relies on the parent IRQ controller to set the
CPU affinity for the IRQ. And this is only valid if there is any wakeup
parent available and defined in DT.

For the case of no parent IRQ controller defined in DT,
msm_gpio_irq_set_affinity() and msm_gpio_irq_set_vcpu_affinity() should
return -EINVAL instead of 0 as the affinity can't be set.

Otherwise, below warning will be printed by genirq:

genirq: irq_chip msmgpio did not update eff. affinity mask of irq 70
