cpufreq: clean up dead code in Kconfig

There is already an 'if CPU_FREQ' condition wrapping these config
options, making the 'depends on' statement for each a duplicate
dependency (dead code).

Leave the outer 'if CPU_FREQ...endif' and remove the individual
'depends on' statement from each option.

This dead code was found by kconfirm, a static analysis tool for
Kconfig.
