Split the common dma.c which shared by Loongson-2E and Loongson-2F, since the code in 'common' directory is assumed be shared by all 64bit Loongson platforms (but Loongson-3 doesn't use it now). By the way, Loongson-2E and Loongson-2F have already dropped 32bit kernel support, so CONFIG_64BIT isn't needed.
