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.
