HID: wacom: Report full pressure range for Intuos, Cintiq 13HD Touch
The new Intuos tablets added in eda01da and the Cintiq 13HD Touch added in b4bf212 are capable of reporting 2048 levels of pressure. Although the kernel reports the correct range to userspace, an oversight has resulted in the driver ingoring the 11th pressure bit and only sending pressures of 0 through 1023. We could fix this issue by expanding the type check to include these devices, but it makes much more sense to just have the driver look at the device's maximum pressure when determining if it should read the 11th bit.
