On heavy storage operations (like database update), the ssp dma
irq can be fired around ~10000/sec.

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.

The icoll code now has an IRQ storm detection mechanism which
will prevent the device from hard freezing in case it happen.
