dma-mapping: handle DMA_ATTR_CPU_CACHE_CLEAN in trace output
commit 6f45b1604cf43945ef472ae4ef30354025307c19 upstream.
Tracing prints decoded DMA attribute flags, but it does not yet
include the recently added DMA_ATTR_CPU_CACHE_CLEAN. Add support
for decoding and displaying this attribute in the trace output.
