  dma-mapping: remove the {alloc,free}_noncoherent methods (2021-02-09 18:01:38 +0100)

----------------------------------------------------------------
dma-mapping updates for 5.12:

 - add support to emulate processing delays in the DMA API benchmark
   selftest (Barry Song)
 - remove support for non-contiguous noncoherent allocations,
   which aren't used and will be replaced by a different API
