sbs-battery.c: Capacity attr = remaining relative capacity

Browse Source 
Currently, the capacity exported by this driver refers to reg 0x0e,
which is the absolute state of charge which according to SBS
refers to the design capacity/ energy of the battery. It can be
> 100 % and drops below 100 % for a fully charged battery with
the battery aging.

This is not what the user exspects of a remaining capacity
indication between 0 and 100 % with 100 % referring to
a fully charged battery. This is provided by SBS reg 0x0d,
which is the relative state of charge referring to the
full charge capacity.
