HID: wacom: generic: Add support for vendor-defined "Sense" usage
Wacom's professional tablets beginning with the Intuos4 are capable of reporting an intermediate degree of proximity where the pen is no longer close enough to communicate with ("in prox"), but still close enough to be sensed ("in range"). This additional state is particularly useful for performing palm rejection as it allows the driver to disable the touch sensor while the pen is a greater distance from the tablet. Like other professional tablets, the new MobileStudio Pro also reports this intermeidate "in range" proximity state. Its descriptor assigns usage 0xff0d0036 to this bit. Normally 'wacom_equivalent_usage' would translate this to the standard HID "Quality" usage, but since this has a different meaning we have it explicitly ignore the usage and define it ourselves as "Sense" (since "In Range" is already defined by the HID standard and interpreted by our driver as meaning "in prox").
