Bug#783214: linux-image-686: Enable HID_BATTERY_STRENGTH config option

[Daniel Nicoletti <dantti12@gmail.com>]

Package: linux-image-686
Severity: wishlist

Dear Maintainer,

since 3.19 the HID_BATTERY_STRENGTH doesn't
requires patching to Kconfig to be enabled
without requiring HID to be built-in.

HID_BATTERY_STRENGTH is an option that allows
for HID devices that support reporting their
battery state (eg Apple Wireless Keyboard/mouse...),
do so by using the power_supply infrastructure,
I've asked Ubuntu and Fedora to enable this in
the past, and has been working well since 3.4 iirc
with 3.19 it's easier so I'd like to have it
enabled on the Debian kernel so we at Tanglu
don't need local patches.

Thanks
