Patch to disable magicmouse battery report support

Hi,

The bluetooth apple magic mouse (hid_magicmouse) disconnects from time to time,
the lower the battery the more often, and reconnects after around 15 seconds.

Rebuild the kernel with CONFIG_HID_BATTERY_STRENGTH=N and the issue disappears,
along with battery status reporting (which otherwise works and can be seen in gnome-shell power control panel).

I've seen this bug since the first introduction of CONFIG_HID_BATTERY_STRENGTH, but it wasn't that of a problem since that config has been off by default until recently.

Code contributions must be made via the linux-bluetooth@ mailing-list, not through bugzilla.
