The Arizona and Madera codecs all have a datasheet name of "MICVDD"
for the regulator output. But future codecs with a regulator that
can be controlled by this driver have different naming convention
for the output of the regulator.

Move the setting of the supply name from arizona_micsupp_common_init()
to arizona_micsupp_probe() and madera_micsupp_probe().
