[ Upstream commit 3da435063777f8d861ba5a165344e3f75f839357 ]

Microsoft Modern Wireless Headset (appearing on the host as "Microsoft USB Link") has a playback and a capture mixer volume/switch, but they are fairly broken. The descriptor reports wrong dB ranges for playback, and the capture volume/switch don't influence on the actual recording at all. Moreover, there seem instabilities in the connection, and at best, we should disable the runtime PM.

So this ended up with a quirk entry for: - Correct the playback dB range; I picked up some reasonable values but it's a guess work - Disable the capture mixer; it's completely useless and confuses PA/PW - Suppress get-sample-rate, apply the delay for message handling, and suppress the auto-suspend

The behavior of the wheel control on the headset is somehow flaky, too, but it's an issue of HID.
