Simplifies the code in several places, and you don't need to use DT or
ACPI, it probes just fine anyway you normally add an I2C device.

All we are dropping here is the platform_data way of specifying mic-bias
voltage, which if you are wanting to do that in an out-of-tree board
file, then I'm sure you can locally modify this driver to use your
wanted voltage setting by default.
