imx233: use tick insteaf of msec to collect statistics

Browse source 
The current code uses the msec irq to collect statistics and
detect irq storms (debug). But this irq is triggered 1000 times
per sec and we don't need that accuracy. This commit removes the
msec irq and use the tick timer instead which is triggered only
100 times per second.
