greybus: audio: Enable codec module detection on different slots 

driver_name associated with dev_name was hard coded earlier.
This limits, audio codec module to be detected on Port#5 only.

Now, driver_name is generated dynamically based on dev_name.
This enables codec module detection on any 1x2 slot.

Also, Update dev_id based on slot number, instead of bundle->id.
bundle->id is not unique for multiple modules added, thus now
using slot number for unique identification.
