The names of the idle states in the output of cpupower monitor command are
truncated to 4 characters. On POWER9, this creates ambiguity as the states
are named "stop0", "stop1", etc.

This patch modifies the output to print the state name that results in a
legible output. The names will be printed with atmost 1 padding in left.
