[PATCH v2 0/4] Hid: add Apple Magic Mouse 2 support

[John Chen <johnchen902@gmail.com>]

The HID descriptor of Magic Mouse 2 contains BTN_LEFT, BTN_RIGHT, REL_X,
REL_Y, whether it's charging, whether it's fully charged, and battery
capacity.

As hidinput can handle the BTNs and RELs, the Magic Mouse 2 already
functions as a basic mouse. Nevertheless, It should be reasonable to
extend hid-magicmouse to support Magic Mouse 2 as well. Furthermore,
hidinput is patched to handle the battery capacity.

This work is based on Recardo's, which is in turned based on Rohitpid's.
Their GitHub repositories are linked below:

Change v1->v2: An extra parameter is passed to hidinput_setup_battery
instead of directly modifying battery_{min,max}.
