ALSA: usb-audio: add Studio 1824 support

Browse Source 
Adapt the already implemented support for the Studio 1824c
audio interface to the predecessor Studio 1824.

Basically just a change adding the
different hardware ID in the relevant places.

Tested as much as possible.
All implemented functionality seemingly works.
