ASoC: SOF: topology: Make control parsing IPC agnostic

Make the control parser in topology IPC agnostic by introducing 2 new
topology IPC ops, control_setup and control_free. These ops handle
setting up/freeing the control data in the IPC format based on the IPC
version.

Along with this, modify the struct snd_sof_control to remove the
IPC-specific field, control_data and replace it with the void pointer to
ipc_control_data. Also, add a few new fields to store all the
information parsed from topology.

Finally, define and set the control setup/free ops for IPC3.
