Not really.  The thing is that historically drivers set the MFP mappings
up themselves rather than letting the board code do it.  Going forward
that should be being done by the platform code but simply removing the
configuration for PXA2xx would break existing users.

Aside from that the PXA3xx series provide multiple MFP options for the
AC97 interface so we can't do an unconditional setup for them anyway -
the configuration is always board specific.
