Yes, we need to use the prefix in codec confs when there are two device instances.

There are always two amps on the board for stereo output. If the two amps sharing
one enable pin, ODM will implement only one device instance in the ACPI table
because there is only one GPIO to control in codec driver.
I'll upload a v3 with more comment.
