Provide robustness against low quality FLL sync clocks by increasing the
timeout for lock to an absurdly high point; we should never get anywhere
near hitting the timeout in a real system unless it is failing.

Arizona devices support two output system clocks. Provide support for
configuring these via set_sysclk(). Once the clock API is more useful
we should migrate over to that.

Some Arizona chips have a higher frequency for the FLL VCO, support this
in the common code.

If an audio interface is configured to use ASYNCCLK then update the
asynchronous sample rate rather than one of our primary sample rates.

Allow any BCLK which can be divided down to generate LRCLK, not just the
lowest possible BCLK to clock out the samples.

Allow the user to select which of the system clocks each AIF is referenced
to and constran the DAI to the set of frequencies which can be generated
from that clock.

They're the rates for the BCLK, not for the sample rate, so rename so that
we don't confuse ourselves.

The Wolfson Arizona series of audio hub CODECs can share a large amount
of their driver code as the result of a common register map. This patch
adds some of this core support, providing a basis for the initial WM5102
audio driver.
