tda998x_configure_audio() is called via some paths where an error return is meaningless, and as a result of moving the audio routing code, this function no longer returns any errors, so let's make it void. We can also make tda998x_write_aif() return void as well. tda998x_configure_audio() also only ever needs to write the current audio settings, so simplify the code in tda998x_audio_hw_params() so that can happen.
