ASoC: max98373: Added controls for autorestart config 



3 new controls are added.
"OVC Autorestart Switch" : controls whether or not the speaker amplifier
automatically re-enables after an overcurrent fault condition.
"THERM Autorestart Switch" : controls whether or not the device
automatically resumes playback when the die temperature recovers from
thermal shutdown.
"CMON Autorestart Switch" : controls whether or not the device
automatically resumes playback when the clock returns after stopping.

Above Auto Restart functions are enabled by default.
