Subject: [PATCH 2/3] ASoC: sh: rz-ssi: Propagate error codes returned from platform_get_irq_byname()

Propagate error codes returned from platform_get_irq_byname() instead of
returning -ENODEV. platform_get_irq_byname() may return -EPROBE_DEFER, to
handle such cases propagate the error codes.

While at it drop the dev_err_probe() messages as platform_get_irq_byname()
already does this for us in case of error.
