Add support for UC-Logic Tablet TWHA60.
It is known to be sold as Genius EasyPen M610 and Monoprice MP1060-HA60.

As this tablet has several variations with different number and different
assignments of frame buttons, they are simply mapped to F1-F24 range and are
left for users to remap in userspace.
