regmap: allow regmap instances to be named
Some devices have multiple separate register regions. Logically, one regmap would be created per region. One issue that prevents this is that each instance will attempt to create the same debugfs files. Avoid this by allowing regmaps to be named, and use the name to construct the debugfs directory name.
