ASoC: rt5677: Add OF device ID table
[ Upstream commit 7b87463edf3e2c16d72eeea3d1cf3c12bb5487c6 ]
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.
