The DAPM widgets are now insntantiated by the core when creating the card
so there is no need for the individual CODEC drivers to do so.

snd_soc_init_card() is always called as the last part of the CODEC probe
function so we can factor it out into the core card setup rather than
have each CODEC replicate the code to do the initialiastation. This will
be required to support multiple CODECs per card.

Don't use a static for WM8974 PLL factors - we don't support more than
one device so it won't happen but no sense in leaving the race condition
hanging around.  Also, pre_div is a single bit and it's a bit simpler if
we move the handling of the factor of 4 in the output into the
coefficient setup.

More and more devices feature PLLs and FLLs with the ability to select
between multiple input clocks. In order to better support these devices
a new argument, source, has been added to the set_pll() configuration
API. Using set_clkdiv() is often difficult due to the need to stop the
PLL/FLL before any reconfiguration can be done.

The device is a mono device but it can read two channel data and
many I2S controllers only understand 2 channels.

The WM8974 is a low power, high quality mono CODEC designed for portable
applications such as digital still cameras or digital voice recorders.

This driver was originally written by Graeme Gregory and Liam Girdwood
and has since been maintained by myself with some updates contributed by
Brett Saunders and Javier Martin.
