[PATCH 2/4] Input: wacom_w9000 - rely on touchscreen_parse_properties() for resolution

[Dmitry Torokhov]

The input core's touchscreen_parse_properties() helper now parses the
touchscreen-x-mm and touchscreen-y-mm properties and calculates axis
resolution in units per millimeter automatically, including handling
axis swapping.

Rely on touchscreen_parse_properties() to configure axis resolutions and
remove the manual property parsing and resolution assignment block in
wacom_w9000_probe(), along with the now-unused local variable.
