HID: magicmouse: Adjust major / minor axes to scale
By visual inspection, the reported touch_major and touch_minor axes are roughly a factor of four too small. The factor is approximate, since the protocol is not known and the HID report encodes touch size with fewer bits than positions. This patch scales the reported values by a factor of four.
