ncr5380: Use DMA hooks for PDMA
Those wrapper drivers which use DMA define the REAL_DMA macro and those which use pseudo DMA define PSEUDO_DMA. These macros need to be removed for a number of reasons, not least of which is to have drivers share more code. Redefine the PDMA send and receive hooks as DMA setup hooks, so that the DMA code can be shared by all 5380 wrapper drivers. This will help to reunify the forked core driver.
