unify DMA_..BIT_MASK definitions: v3.1

Browse source 
Remove redundant DMA_..BIT_MASK definitions across two drivers.  The
computation of the majority of the bitmasks is done by the compiler.  The
initial split of the patch touching each a different file got removed due
to possible git bisect breakage.
