Add LiMn (one of the most common for small non-rechargable batteries)
battery technology and voltage_min/_max properties support.

@ -87,6 +87,10 @@ batteries use voltage for very approximated calculation of capacity.
Battery driver also can use this attribute just to inform userspace
about maximal and minimal voltage thresholds of a given battery.
VOLTAGE_MAX, VOLTAGE_MIN - same as _DESIGN voltage values except that
these ones should be used if hardware could only guess (measure and
retain) the thresholds of a given power supply.
CHARGE_FULL_DESIGN, CHARGE_EMPTY_DESIGN - design charge values, when
battery considered full/empty.
