From: Nikolai Kondrashov <spbnick@gmail.com>
Add support for touch ring to UC-Logic driver. The touch ring reports
can be flipped around a specific point to match the orientation and
direction reported by the Wacom drivers. The proximity will also be
reported similar to the Wacom drivers.

Support assigning custom device name suffixes to frame input devices
instead of just "Pad". This allows distinguishing multiple frame input
devices, e.g. for Huion HS610.

Allow three frame parameter sets per each UC-Logic tablet interface.
Bump the number of supported subreports to three as well to accommodate
ID routing. This allows supporting the dial on Huion Q620M.
