[ARM] 3579/1: AT91RM9200 Timer simplification
Patch from Andrew Victor
Use a global variable 'last_crtr' to store the time of the last timer
tick instead of the ST_RTAR register.
It's faster, frees up the ST_RTAR register for other uses, and hopefully
makes the code more understandable. [Patch from Peter Menzebach]
Also add the SA_TIMER flag to Timer IRQ. (It seems to be required for
the realtime preempt patch).
