sbs-battery: Probe should try talking to the device
Turns out this driver doesn't actually try talking to the device at
probe time, so if it's incorrectly configured in the device tree or
platform data (or if the battery has been removed from the system),
then probe will succeed and every access will sit there and time out.
The end result is a possibly laggy system that thinks it has a battery
but can never read status, which isn't very useful.
Instead, just read any register (I chose status) at probe, and if that
fails, don't register the device.
