It will get DAI ID from OF graph "port", but, we want to consider about

And, we also want to keep compatibility.

This patch fixup it as

	if (driver has specified DAI ID)
		use it as DAI ID
	else if (OF graph endpoint has reg)
		use it as DAI ID
	else if (OF graph port has reg)
		use it as DAI ID

As opposed to what was initially noted in the toddr dai driver, the spdifin
does not place the msb at bit 28, it just output a whole spdif subframe.

Placing the msb at bit 28 in the toddr driver just filters out the parity,
user, channel status and validity bits. It is better to just provide the
whole spdif subframe to the userspace and let the iec958 plugin deal with

we can avoid non-existing register access.
