HID: uclogic: Add frame type quirk

The report descriptor used to get information about UGEE v2 devices is
incorrect in the XP-PEN Deco Pro SW. It indicates that the device frame
is of type UCLOGIC_PARAMS_FRAME_BUTTONS but the device has a frame of
type UCLOGIC_PARAMS_FRAME_MOUSE.

Here is the original report descriptor:

  0x0e 0x03 0xc8 0xb3 0x34 0x65 0x08 0x00 0xff 0x1f 0xd8 0x13 0x00 0x00
                                     ^ This byte should be 2

Add a quirk to be able to fix the reported frame type.
