hwmon: (max6621) fix temperature clamp range
MAX6621_TEMP_INPUT_MIN and MAX6621_TEMP_INPUT_MAX are used to clamp the
writable offset and critical thresholds. They are defined as -127000 and
128000.
The driver decodes the temperature through an s8 and its own comment in
max6621_read() documents an 8-bit two's complement value, whose range is
-128 to +127 degrees C. The current limits therefore reject the valid
-128 degrees C and accept +128 degrees C, which does not fit the 8-bit
range.
Correct the limits to -128000 and 127000.
