ASoC: SDCA: expose class SoundWire probe/remove as library
Split the internal class_sdw_probe/class_sdw_remove functions into
caller-friendly library helpers:
sdca_class_probe(sdw, drv)
sdca_class_remove(drv)
The class_sdw_probe/class_sdw_remove callbacks of the built-in
class_sdw_driver are now thin wrappers that allocate a bare
sdca_class_drv, stash it in drvdata, and defer to the exported
helpers.
The exported sdca_class_probe() takes a caller-owned struct
sdca_class_drv * so codec-specific SoundWire drivers can embed the
class state in their own priv struct, own dev_set_drvdata() themselves,
and avoid a second allocation. No functional change for the built-in
driver.
This lays the groundwork for codec-specific SDCA SoundWire drivers
that want to compose the class-side probe with their own quirks; the
next patches add the class_ops mechanism on top.
