1b6e8cba62 imx233: make sure dma descriptors are cache friendly 
Because DMA descriptors needs to be committed and discarded from
the cache, if they are not cache aligned and/or if their size
is not a multiple of cache ligne, nasty side effects could occur
with adjacents data. The same applies to DMA buffers which are
still potentially broken. Add a macro to ensure that these
constraints will not break by error in the future.

9ced006c06 imx233: move icoll stuff to its own file 
The icoll code now has an IRQ storm detection mechanism which
will prevent the device from hard freezing in case it happen.

645680d62b imx233: add pinctrl debug code to track pin uses 
Past development has proved that one can mistakely use
the same pin for two uses without noticing. Since this
causes extremely hard to find bugs, the infrastructure
will allow to register pin uses and panic when a conflict
is detected. The pinctrl debug now shows the pin uses
when its support is compiled in.
