Daniel Mack 23caaf19b1 ALSA: usb-mixer: Add support for Audio Class v2.0
USB Audio Class v2.0 compliant devices have different descriptors and a
different way of setting/getting min/max/res/cur properties. This patch
adds support for them.

Daniel Mack 99fc86450c ALSA: usb-mixer: parse descriptors with structs
Introduce a number of new structs for mixer, selector, feature and
processing units and some static inline helpers to access fields which
have dynamic offsets. Use them in mixer.c to parse the descriptors. This
is necessary for the upcoming audio v2 parsers.
