`cpupower frequency-info` supports the '--boost' option since the program
was first added with commit 7fe2f6399a84 ("cpupowerutils - cpufrequtils
extended with quite some features"), but the man page lacks it.

'--epp' has been added with commit 5f567afc283f ("cpupower: Add support for
showing energy performance preference") but it has never been added to the
man page.

cpufreq-info.c:
	{"boost",	 no_argument,		 NULL,	 'b'},
	...
	{"epp",		 no_argument,		 NULL,	 'z'},
