hwmon: (ibmpex) Allow format string checking
The only difference between the three power_sensor_name_templates is
whether there is a suffix of "", "_lowest" or "_highest". We might as
well pull those into an array and use a literal format string,
allowing gcc to do type checking of the arguments to
sprintf. Incidentially, the same three suffixes are used in the
temp_sensor_name_templates case, so we end up eliminating one static
array.
