a092986fc0 HID: uclogic: Parse the UGEE v2 frame type
The string descriptor returned by UGEE v2 devices contains a byte
indicating the device frame type.

The values discovered so far are:

 - 0: Frame with buttons, present in the XP-PEN Deco L.
 - 1: Frame with buttons and dial, present in the PARBLO A610 PRO.
 - 2: Frame with buttons and a mouse, shaped as a dial + touchpad.
      Present in the XP-PEN Deco Pro S.

Parse the frame type and add KUnit tests.

a64cbf3ce6 HID: uclogic: Refactor UGEE v2 string descriptor parsing
The UGEE v2 tablets expose a string descriptor with their capabilities.

Move the code used to parse the descriptors and generate a parameter
list from it to its own function and add KUnit tests to validate the
parser.
