arm64: Fix duplicated Kconfig entries
Probably due to rebasing over the lengthy time it took to get the patch
merged commit addea9ef055b (cpufreq: enable ARM drivers on arm64) added
a duplicate Power management options section. Add CPUfreq to the CPU
power management section and remove a duplicate include of the main
power section.
