ASoC: AC97 doesn't use regmap by default
Since commit 38cbf959 ("ASoC: core: Try to use regmap if the driver doesn't set up any I/O") any ASoC codec which doesn't set codec::control_data is assumed to use regmap. That doesn't work with AC97 so this workaround sets the codec::control_data member to a random value to restore proper behaviour. Tested with WM9712.
