[PATCH 7/7 v3] HID: magicmouse: Adjust major / minor axes to scale

[Chase Douglas <chase.douglas@canonical.com>]

From: Henrik Rydberg <rydberg@euromail.se>

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.
