[PATCH 3/3] power/ds2760_battery: use factor of 20 for rated_capacity

[Daniel Mack]

In the ds2760 driver, the currently used factor of 10 to store the rated
battery capacity internally is not sufficient for batteries > 2.55 Ah,
as the 8-bit register will overflow for bigger values.

Change the factor to 20 to broaden that range. Note that due to
RATED_CAPACITY_FACTOR, the external interface won't change, neither for
the writeable sysfs entires nor for the kernel rated_capacity module
parameter.
