ASoC: AC97 doesn't use regmap by default
Since commit 38cbf9598feba97de9f9b43efa9153fd7c1a2ec9
("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.
