A new clock driver makes more sense if it can be used from consumers like cpufreq. Before we enable the driver we must tell the config that the RTL838X and RTL839X targets allow CPU frequency changing. Even though these targets currently rely on the CPU's internal R4K timer, MIPS_EXTERNAL_TIMER is selected to allow for CPU frequency change testing. The Realtek timers, which are clocked by the Lexra bus, still need to be supported and used in order to provide correct wall times when reclocking the CPU.
