[PATCH] ALSA: scarlett2: Add Focusrite Clarett+ 8Pre support

From: Christian Colglazier <christian at cacolglazier.com>
The Focusrite Clarett+ 8Pre uses the same protocol as the Scarlett Gen
2 and Gen 3 product range. This patch adds support for the Clarett+
8Pre by adding appropriate entries to the scarlett2 driver.
The Clarett+ 2Pre and 4Pre, and the Clarett USB product line
presumably use the same protocol as well, so support for them can
easily be added if someone can test.
