ASoC: SOF: ipc4-topology: Add definition for generic switch/enum control

Browse source

Currently IPC4 has no notion of a switch or enum type of control which is
a generic concept in ALSA.

The generic support for these control types will be as follows:
- large config is used to send the channel-value par array
- param_id of a SWITCH type is 200
- param_id of an ENUM type is 201

Each module need to support a switch or/and enum must handle these
universal param_ids.
The message payload is described by struct sof_ipc4_control_msg_payload.
