This adds the constant-charge-current property to the list of optional
properties for the battery.
The constant charge current is critical for batteries as they can't
handle all charge currents.
Signed-off-by: Quentin Schulz <quentin.schulz@free-electrons.com>

v4:
- switch from constant-charge-current-microamp to constant-charge-microamp,
added in v3
