Log Message:
PXA270 uses a 3.25Mhz clock for OS timers, not 3.6864Mhz.

Also while here fix the delay loop used before timers are enabled to
cause a delay, by using a volatile int to do a countdown.  gcc has become
intelligent enough to optimize an empty loop away.

For delay on PXA270 we should use one of the other counters, and a 1Mhz
clock, so that we don't have to computer the counter increment.

XXX: also looks like there's a bug if the counter wraps, as delay doesn't
look like it allows for that.
