Subject: [PATCH v3 3/5] dt-bindings: touchscreen: add touchscreen-x/y-plate-ohms property
Te calculate the pressure on a restrictive touchscreen we need need to
know resistance at least of X plate. Some calculations need to use both
X and Y values.
So, add generic properties which can be used by all drivers
