sbs-battery: add min design voltage to sbs-battery
sbs-battery: add min design voltage to sbs-battery

sbs-battery has a max design voltage but not a min design voltage field.
The SBS spec only has one design voltage:

Currently this is being used for max design voltage.  This patch uses it
for min design voltage as well.
