media: videobuf2: add queue memory coherency parameter
Preparations for future V4L2_MEMORY_FLAG_NON_COHERENT support.
Extend the vb2_core_reqbufs() parameters list to accept requests'
->flags, which will be used for memory coherency configuration.
An attempt to allocate a buffer with coherency requirements
that do not match the queue's consistency model will fail.
