GENERIC_TIME and GENERIC_CLOCKEVENTS support for the at91rm9200. - Oneshot mode (used for NO_HZ and high res timers) uses the alarm to emulate a real oneshot timer; the trickiest bit is how to avoid some lowlevel races. Thanks to Remy Bohmer for various fixes to this code. - Tighten up periodic mode support using the PIT. - Streamline reads of the 32KHz counter. Thanks to Marc Pignat for some testing results: the CRTR register has *very* odd behavior. The reread appears to work around stranger glitches than just getting an old clock value (which would quickly self-correct). - Remove the rounding-up of tick_usec to 10.009 msec (32KiHz/100), since that no longer acts correct (time increases too fast). Note that the at91sam9 and at91x40 chips need other solutions, since they don't have the same system timer module.
