cma: decrease CMA_ALIGNMENT lower limit to 2
On an embedded system with a tiny (1 MiB) CMA area for video memory, and a simple enough video pipeline, we can decrease the CMA_ALIGNMENT by a factor of 2 to avoid wasting memory, as all the allocations for video buffers will be of the exact same size (dictated by the size of the screen).
