Mercier" The docs for dma_heap_get_name were incorrect, and since they were duplicated in the header they were wrong there too. The docs formatting was inconsistent so I tried to make it more consistent across functions since I'm already in here doing cleanup. Remove multiple unused includes and alphabetize.
