HID: hid-magicmouse: Magic Trackpad has 1 button, not 2
hid-magicmouse was advertising the Apple Magic Trackpad as having 2 buttons (left and right) when it actually only has 1 button. Advertising multiple buttons makes Xorg disable all button 2 and 3 emulation (using multi-finger clicks). So Xorg users don't get working right/middle-click emulation out of the box. This patch makes hid-magicmouse correctly only report one real button for Magic Trackpad, which in turn makes Xorg enable multi-finger click support to emulate right/middle buttons.
