HID: magicmouse: Correct report range of major / minor axes
In patch "HID: magicmouse: Adjust major / minor axes to scale", touch_major and touch_minor axes are scaled by a factor of four when reported but the max touch_major/minor is not scaled accordingly. This patch scales the max touch_major/minor to be consistent with the reported value.
