ASoC: tfa9879: Export OF device ID as module alias

The I2C core always reports a MODALIAS of the form i2c:<foo> even if the device was registered via OF, this means that exporting the OF device ID table device aliases in the module is not needed. But in order to change how the core reports modaliases to user-space, it's better to export it.

Before this patch:

$ modinfo sound/soc/codecs/snd-soc-tfa9879.ko  | grep alias
alias:          i2c:tfa9879

After this patch:

$ modinfo sound/soc/codecs/snd-soc-tfa9879.ko  | grep alias
alias:          i2c:tfa9879
alias:          of:N*T*Cnxp,tfa9879C*
alias:          of:N*T*Cnxp,tfa9879

Looks ok to me,
