Subject: [PATCH] HID: uclogic: Add support for recent Huion tablets

Since Huion uses a new device id for recent tablets, add a new
device id 0x0064 to support recent Huion tablets.

At least these tablets are using device id 0x0064:

Gaomon 1060 Pro (0x256c:0x0064)
Gaomon M6       (0x256c:0x0064)
Huion KD200     (0x256c:0x0064)
Huion KD100     (0x256c:0x0064)

This patch was tested on Gaomon 1060 Pro and Huion KD200. This patch
may affect other models with the same id, however, it's seems that the
other models of Huion do not have incompatible hardware changes, so
this patch should still work.
