ALSA: scarlett2: Add support for air/phantom control on input 2
The Focusrite Scarlett Gen 4 Solo has Air and Phantom Power controls
on analogue input #2 (the Gen 3 Solo had these controls on analogue
input #1). Add air_input_first and phantom_first device info options
to cater for this.
These options are similar to the level_input_first option that was
added for the Gen 3 Solo, but these new options do not require
adjusting the index of the control.
