[PATCH] ASoC: tlv320aic26: remove keyclick sysfs file

[Pengpeng Hou]

aic26_probe() creates the keyclick sysfs file on the component device.
The file callback uses the ASoC component pointer stored in the driver
private data.

There is no matching remove callback, so the sysfs file can remain after
the component is removed while its backing component state is gone.

Add a component remove callback that removes the keyclick file.
