Yes.

ASoC doesn't really support the enumeration very well, you can use
ac97.c as the CODEC but that's about it.  There is a generic AC'97 PXA
driver in sound/arm, if your system can use that that'd be a better
route to DT integration for it I think.  Did you try that, if there are
problems with that perhaps we can improve that driver, it should  be
simpler.
