In order to constify `snd_soc_component_driver` struct, simplify the logic
and the `sti_sas_dev_data` struct.
Since commit 165a57a3df ("ASoC: sti-sas: clean legacy in sti-sas") only
only chip is supported and `sti_sas_driver` can be fully defined at
compilation time.

The maple tree register cache is based on a much more modern data structure
than the rbtree cache and makes optimisation choices which are probably
more appropriate for modern systems than those made by the rbtree cache. In
v6.5 it has also acquired the ability to generate multi-register writes in
sync operations, bringing performance up to parity with the rbtree cache
there.
Update the sti-sas driver to use the more modern data structure.

Some registers accesses are done in atomic context.
Enable fast io to use spinlock instead of mutex to protect access.

codec driver and component driver has duplicated callback functions,
and codec side functions are just copied to component side when
register timing. This was quick-hack, but no longer needed.
This patch moves these functions from codec driver to component driver.
