imx233: add more icoll statistics
Those new statistics give the maximum time an IRQ took and also the total time spent in IRQ, for each IRQ. Hopefully those do not take took much time or space to collect. If this is the case, it can be enabled in debug builds only the future. Change-Id: I05af172897c5cb7ffcc9322452f974d8f968e29d
