ASoC: uda1380: Add OF device ID table



The driver doesn't have a struct of_device_id table but supported devices
are registered via Device Trees. This is working on the assumption that a
I2C device registered via OF will always match a legacy I2C device ID and
that the MODALIAS reported will always be of the form i2c:<device>.

But this could change in the future so the correct approach is to have an
OF device ID table if the devices are registered via OF.

Before this patch:

$ modinfo sound/soc/codecs/snd-soc-uda1380.ko | grep alias
alias:          i2c:uda1380

After this patch:

$ modinfo sound/soc/codecs/snd-soc-uda1380.ko | grep alias
alias:          of:N*T*Cnxp,uda1380C*
alias:          of:N*T*Cnxp,uda1380
alias:          i2c:uda1380
