CPUFreq driver's Kconfig entries are added in Kconfig.<arch> files and they are all included from the main Kconfig file using a menu entry. This creates another level of (unnecessary) hierarchy within the menuconfig entries.

The problem occurs when there are drivers usable across architectures. Either their config entry is duplicated in all the supported architectures or is put into the main Kconfig entry. With the later one, we have menuconfig entries for drivers at two levels then.

Fix these issues by getting rid of another level of menuconfig hierarchy and populate all drivers within the main cpufreq menu. To clearly distinguish where the drivers start from, also add a comment that will appear in menuconfig.

Queued up for 3.19-rc1, thanks!
