ASoC: dwc: Propagate -EPROBE_DEFER from IRQ lookup

Browse Source 
platform_get_irq_optional() never returns 0. It returns a positive IRQ
number on success or a negative error code on failure.

Return -EPROBE_DEFER from platform_get_irq_optional() so the driver is
re-probed when the interrupt resource becomes available instead of
continuing probe without an IRQ.
