DmaMap () only allows uncached mappings to be used for creating consistent mappings with operation type MapOperationBusMasterCommonBuffer. However, if the buffer passed to DmaMap () happens to be aligned to the CWG, there is no need for a bounce buffer, and we perform the cache maintenance directly without ever checking if the memory attributes of the buffer adhere to the API. So add some debug code that asserts that the operation type and the memory attributes are consistent.
