HID: Wacom: switch Dell canvas into highres mode 

The Dell Canvas exports 2 collections for the Pen part. The only
difference between the 2 is that the default one has half the resolution
of the second one.

The Windows driver switches the tablet into the second mode, so we should
behave the same.
