ASoC: cs43130: Constify snd_soc_component_driver struct
In order to constify `snd_soc_component_driver` struct, duplicate
`soc_component_dev_cs43130` into a `soc_component_dev_cs43130_digital` and
`soc_component_dev_cs43130_analog`.
These 2 new structures share the same .dapm_widgets and .dapm_routes
arrays but differ for .num_dapm_widgets and .num_dapm_routes.
In the digital case, the last entries are not taken into account.
Doing so has several advantages:
- `snd_soc_component_driver` can be declared as const to move their
declarations to read-only sections.
- code in the probe is simpler. There is no need to concatenate some
arrays to handle the "analog" case
- this saves some memory because all_hp_widgets and analog_hp_routes can
be removed.
