MIPS: Alchemy: RTC counter clocksource / clockevent support.
Add support for the 32 kHz counter1 (RTC) as clocksource / clockevent
device. As a nice side effect, this also enables use of the 'wait'
instruction for runtime idle power savings.
If the counters aren't enabled/working properly, fall back on the
cp0 counter clock code.
