Don't assume that touch devices report per finger width and pressure
The palm detection relies on both the width and the pressure.
a897147be04 ("Use ABS_MT events for the palm detection when supported")
assumed that all the touch devices can report both ABS_MT_TOUCH_MAJOR
and ABS_MT_PRESSURE, but this is not necessarily true. This assumption
could hence break the palm detection when at least one of the mentioned
events is not declared but both ABS_TOOL_WIDTH and ABS_PRESSURE are
reported.
