[MIPS] Only build r4k clocksource for systems that work ok with it.
In particular as-is it's not suited for multicore and mutiprocessors systems where there is on guarantee that the counter are synchronized or running from the same clock at all. This broke Sibyte and probably others since the "[MIPS] Handle R4000/R4400 mfc0 from count register." commit. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
