[PATCH v4 6/6] cpupower-info.1: describe the --perf-bias option

[Roberto Ricci <io@r-ricci.it>]

The cpupower-info(1) man page only mentions the short form of the
'--perf-bias' option in the synopsys, but the long form is not documented
and its effect is not explained.

cpupower-info.c:
     {"perf-bias", optional_argument, NULL, 'b'},
