Well, it's a very unusual hardware design choice to have multiple I2C
endpoints in a single physical chip.

With regmap it should be very straightforward to reuse the same driver
for both standalone and non-standalone versions, just a small amount of
glue code in the CODEC driver I'd expect.  Usually the bus level code is
tiny.
