[PATCH] backlight/arcxcnn support newer chips in arcxcnn family and fix vendor prefix

[Brian Dodge]

Support for ArcticSand arc1 and arc3 ships is added. Some ranges
and control paths are modified based on the chip id probed via
i2c. Also updates vendor prefix to arctic from arc which was a
mistake in the original driver submission
