Christoph Hellwig 961729bfc7 openrisc: remove the partial DMA_ATTR_NON_CONSISTENT support
The openrisc DMA code supports DMA_ATTR_NON_CONSISTENT allocations, but
does not provide a cache_sync operation.  This means any user of it
will never be able to actually transfer cache ownership and thus cause
coherency bugs.
