mmc: Define a constant for the maximum block size
The number 512 appears quite a bit in the mmc code. Add a constant for this so that it can be used here and in other parts of the code (e.g. SPL code which loads from mmc). Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Vadim Bendebury <vbendeb@google.com>
