[PATCH 05/28] media/v4l2: remove V4L2-FLAG-MEMORY-NON-CONSISTENT

weird gymanstics with the DMA_ATTR_NON_CONSISTENT flag, which is
unimplemented except on PARISC and some MIPS configs, and about to be
removed.

a saner API for allocating DMA addressable pages v3
Hi all,
this series replaced the DMA_ATTR_NON_CONSISTENT flag to dma_alloc_attrs

ensures that other drivers that have asked for better support for
non-coherent DMA to pages with incurring bounce buffering over can finally
be properly supported.
