It would be useful to explain why a platform driver would need to make
use of codec-management related routines, which would typically be
needed only in a codec or machine driver, or hidden as part of a generic
bus layer.

In addition, both the Skylake and SOF/HDA drivers make use of e.g.,
snd_hdac_ext_bus_device_init(), what was wrong with this approach that's
been used since 2018?
