dma-buf: move dma-buf symbols into the DMA_BUF module namespace
In order to better track where in the kernel the dma-buf code is used,
put the symbols in the namespace DMA_BUF and modify all users of the
symbols to properly import the namespace to not break the build at the
same time.
Now the output of modinfo shows the use of these symbols, making it
easier to watch for users over time:
$ modinfo drivers/misc/fastrpc.ko | grep import
import_ns: DMA_BUF
