The irq_set_affinity callback should not be set if parent IRQ domain
doesn't present because gpio-tegra driver callback fails in this case,
causing a noisy error messages on system suspend:
Disabling non-boot CPUs ...
IRQ 26: no longer affine to CPU1
IRQ128: set affinity failed(-22).
IRQ130: set affinity failed(-22).
IRQ131: set affinity failed(-22).
IRQ 27: no longer affine to CPU2
IRQ128: set affinity failed(-22).
IRQ130: set affinity failed(-22).
IRQ131: set affinity failed(-22).
IRQ 28: no longer affine to CPU3
IRQ128: set affinity failed(-22).
IRQ130: set affinity failed(-22).
IRQ131: set affinity failed(-22).
Entering suspend state LP1
Hence just don't specify the irq_set_affinity callback if parent PMC
IRQ domain is missing. Tegra isn't capable of setting affinity per GPIO,
affinity could be set only per GPIO bank, thus there is nothing to do
for gpio-tegra in regards to CPU affinity without the parent IRQ domain.
