ALSA: usb-audio: Fix Focusrite Scarlett 6i6 gen1 - input handling
The Scarlett 6i6 has no padding on rear inputs 3/4 but a gainstage. This patch introduces this functionality as to be seen in the mac or windows scarlett control. The correct address could already be found in the dump info, but was never used. Without this patch inputs 3/4 are quite unusable else.
