ALSA: usb-audio: Add quirk for PreSonus AudioBox USB

Browse Source 
The PreSonus AudioBox USB (0x194f:0x0301) only supports S24_3LE
format for both playback and capture. It does not support S16_LE
despite being a USB full-speed device. Add explicit format quirks
for both the playback (interface 2) and capture (interface 3)
interfaces to ensure correct format negotiation.
