Input: bcm5974 - adjust major/minor to scale

By visual inspection, the reported touch_major and touch_minor axes are a factor of two too small. Presumably the device actually reports the semi-major and semi-minor axes. Corrected with this patch. Signed-off-by: Henrik Rydberg <[email protected]> Signed-off-by: Dmitry Torokhov <[email protected]>
