Sure, but what I don't want in that DAI driver is conditional code
because of different clock names on different chips.  For example,
some devices may only have one clk, so the hardware name is actualy
"mcasp" instead of "mcasp0" etc.

IOW, there will always be conditional code, I would prefer it not to
be in sound/soc/* and rather see it in the chip/board specific init
