ASoC: constify snd_soc_component_driver struct

Declare `snd_soc_component_driver` as const to move it to a read-only
section for the drivers that do not modify the struct after its
declaration.

The affected drivers only pass this struct to
`devm_snd_soc_register_component()`, whose argument is const and
therefore does not modify the content of the struct.
