ALSA: fireworks: add support for Loud Onyx 1200f quirk

Loud Technologies shipped Onyx 1200f 2008 in its Mackie brand and
already discontinued. The model uses component of Fireworks board
module as its communication and DSP function.

The latest firmware (v4.6.0) has a quirk that tx packet includes wrong
value (0x1f) in its dbs field at middle and higher sampling transfer
frequency. It brings ALSA fireworks driver discontinuity of data block
counter.

This commit fixes it by assuming it as a quirk of firmware version
4.6.0.
