ALSA: scarlett2: Add support for reading firmware version

Browse source

The 84 bytes read during initialisation step 2 were previously
ignored. This patch retrieves the firmware version from bytes 8-11,
stores it in the scarlett2_data struct, and makes it available
through a new control "Firmware Version".
