HID: apple: avoid setting up battery timer for devices without battery

Currently, the battery timer is set up for all devices using hid-apple,
irrespective of whether they actually have a battery or not.

APPLE_RDESC_BATTERY is a quirk that indicates the device has a battery
and needs the battery timer. This patch checks for this quirk before
setting up the timer, ensuring that only devices with a battery will
have the timer set up.
