HID: magicmouse: fix battery reporting for Apple Magic Trackpad 2

Battery reporting does not work for the Apple Magic Trackpad 2 if it is
connected via USB. The current hid descriptor fixup code checks for a
hid descriptor length of exactly 83 bytes. If the hid descriptor is
larger, which is the case for newer apple mice, the fixup is not
applied.

This fix checks for hid descriptor sizes greater/equal 83 bytes which
applies the fixup for newer devices as well.
