ASoC: cs35l41: Add ASP TX3/4 source to register patch

The mixer controls for ASP TX3/4 are set to values that are not included in their enumeration control. This will cause spurious event notifications when the controls are first changed, as the register value changes whilst the actual visible enumeration value does not. Use the register patch to set them to a known value, zero, which equates to zero fill, thereby avoiding the spurious notifications.
