Since this CONFIG option will be used for both Loongson-3A/3B machines, and not all Loongson-3 machines are produced by Lemote, we rename CONFIG_LEMOTE_MACH3A to CONFIG_LOONGSON_MACH3X.

This option enables the mfgpt0 timer of AMD CS5536. With this timer

switched on you can not use high resolution timers.

If you want to enable the Loongson2 CPUFreq Driver, Please enable

this option at first, otherwise, You will get wrong system time.
