Subject: [PATCH v5 11/18] ASoC: mediatek: Add common mtk_afe_component_probe callback

Multiple MediaTek AFE PCM component drivers are using their own .probe()
callback, but most of those are simply duplicated functions as they are
doing exactly the same thing over and over.

Add a common probe callback for this component to reduce duplication.
