6.6-stable review patch. If anyone has any objections, please let me know.

From: Geoffrey D. Bennett g@b4.vu
[ Upstream commit bc83058f598757a908b30f8f536338cb1478ab5b ]
Early versions of this mixer driver did not work on all hardware, so out of caution the driver was disabled by default and had to be explicitly enabled with device_setup=1.
Since commit 764fa6e686e0 ("ALSA: usb-audio: scarlett2: Fix device hang with ehci-pci") no more problems of this nature have been reported. Therefore, enable the driver by default but provide a new device_setup option to disable the driver in case that is needed.
- device_setup value of 0 now means "enable" rather than "disable". - device_setup value of 1 is now ignored. - device_setup value of 4 now means "disable".
