Subject: [PATCH] dma-mapping: dma-map-ops.h: Remove an outdated comment

The "/* CONFIG_ARCH_HAS_DMA_COHERENCE_H */" was an description about the
ARCH_HAS_DMA_COHERENCE_H configure option, but it has been removed since
the dma_default_coherent variable was lifted from the mips architecture
to the driver core. Therefore it doesn't match any compile guard now.
Just remove it.

Fixes: 6d4e9a8efe3d ("driver core: lift dma_default_coherent into common code")
