power: supply: bq25890: fix the -10 C NTC lookup entry

The TSPCT lookup table is monotonically decreasing except for ADC code
121, where the sequence reads -9.0 C, -1.0 C, -12.0 C.  This makes the
reported battery temperature jump upward by eight degrees for one code
and then downward by eleven degrees for the next code.

The entry is a missing zero: use -10.0 C so the sequence remains
monotonic between -9.0 C and -12.0 C.
