ASoC: soc-core: add debugfs_prefix member to snd_soc_component_driver
Allow the component debugfs_prefix to be set from
snd_soc_component_driver. First use case is avoiding a duplicate
debugfs entry error in case a device has multiple components
which have the same name therefore.
Note that we don't set component->debugfs_prefix if it's set already.
That's needed because partially component->debugfs_prefix is set
before calling snd_soc_component_initialize().
