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.
