[PATCH] ASoC: Intel: KMB: Propagate -EPROBE_DEFER from IRQ lookup

[phucduc.bui@gmail.com]

From: bui duc phuc <phucduc.bui@gmail.com>

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.
