This feature was undocumented on early A4DJ units. It is indicated by lighting both the 'line' and 'phono' lamps at the same time. Newer units document this and the newer Windows drivers enable this for all units, so restore the functionality.
This patch simplifies the code and changes the mode mapping to match the A8DJ, favouring simpler code and consistency over keeping the existing mapping.
Both 'Control vinyl' and 'Phono' input modes enable the hardware preamp. The difference is the input impedance.
This reverts commit 9a9527e.
