Anssi Hannula eb1a74b7be ALSA: usb-audio: Extend DragonFly dB scale quirk to cover other variants 
The DragonFly quirk added in 42e3121d90 ("ALSA: usb-audio: Add a more
accurate volume quirk for AudioQuest DragonFly") applies a custom dB map
on the volume control when its range is reported as 0..50 (0 .. 0.2dB).

However, there exists at least one other variant (hw v1.0c, as opposed
to the tested v1.2) which reports a different non-sensical volume range
(0..53) and the custom map is therefore not applied for that device.

This results in all of the volume change appearing close to 100% on
mixer UIs that utilize the dB TLV information.

Add a fallback case where no dB TLV is reported at all if the control
range is not 0..50 but still 0..N where N <= 1000 (3.9 dB). Also
restrict the quirk to only apply to the volume control as there is also
a mute control which would match the check otherwise.

* Mapping spdif AES bits to vendor register.bit:
* AES0: [0 0 0 0 2.3 2.2 2.1 2.0] - default 0x00
* AES1: [3.3 3.2.3.1.3.0 2.7 2.6 2.5 2.4] - default: 0x01
* AES2: [0 0 0 0 0 0 0 0]
* AES3: [0 0 0 0 0 0 x 0] - 'x' bit is set basing on standard usb request
* (UAC_EP_CS_ATTR_SAMPLE_RATE) for Audio Devices
*
* power on values:
* r2: 0x10
* r3: 0x20 (b7 is zeroed just before playback (except IEC61937) and set
* just after it to 0xa0, presumably it disables/mutes some analog
* parts when there is no audio.)
* r9: 0x28
*
* Optical transmitter on/off:
* vendor register.bit: 9.1
* 0 - on (0x28 register value)
* 1 - off (0x2a register value)
