Not all CODEC devices have three audio interfaces and the clock rates
which support these things vary. Support this by using driver data to
supply the clock rates and by only completing the parts of system setup
which are required for the system.

The Bells system can take a WM0010 as well as a CODEC - assume there's
one present by default. While we're at it stop using magic numbers for
the DAIs for readability.

The Wolfson Bells board takes submodules for various audio functions but
since the system integrations are virtually identical for most of them we
can support the overwhemling majority from the same machine driver.
