HID: Add support for UC-Logic WP????U tablets

Add support for UC-Logic WP4030U, WP5540U and WP8060U tablets.
These tablets are usually sold by Genius, Trust and possibly others under
different names and in different cases, but with the original USB
vendor/product IDs.

Currently, these tablets are supported by standalone X.org driver WizardPen.
This patch aims to fix them in the kernel and make them supported by the
generic evdev X.org driver. Still, some minor fixes in the X.org driver are
to be made for the full stack support.
