Jeremie Knuesel 48d6b91798 ALSA: usb-audio: Increase delay in MOTU M quirk 
Increase the quirk delay from 2 seconds to 4 seconds. This reflects a
change in the Windows driver in which the delay was increased to about
3.7 seconds. The larger delay fixes an issue where the device fails to
work unless it was powered up early during boot.

Also clarify in the quirk comment that the quirk is only applied to
older devices (USB ID 07fd:0008).
