Currently the ExpressKey Remote battery will persist indefinitely in /sys/class/power_supply. Remove the battery when we stop getting reports from the device.

Also remove some unneccessary code and make an EKR struct name more descriptive.

Only the bugfix in the first patch will be sent to stable.
