Finn Thain 6c4b88ca59 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.

* The card is detected and initialized in one of several ways :
* 1. With command line overrides - NCR5380=port,irq may be
* used on the LILO command line to override the defaults.
*
* 2. With the GENERIC_NCR5380_OVERRIDE compile time define. This is
* specified as an array of address, irq, dma, board tuples. Ie, for
* one board at 0x350, IRQ5, no dma, I could say
* -DGENERIC_NCR5380_OVERRIDE={{0xcc000, 5, DMA_NONE, BOARD_NCR5380}}
*
* -1 should be specified for no or DMA interrupt, -2 to autoprobe for an
* IRQ line if overridden on the command line.
*
* 3. When included as a module, with arguments passed on the command line:
* ncr_irq=xx the interrupt
* ncr_addr=xx the port or base address (for port or memory
* mapped, resp.)
* ncr_dma=xx the DMA
* ncr_5380=1 to set up for a NCR5380 board
* ncr_53c400=1 to set up for a NCR53C400 board
* e.g.
* modprobe g_NCR5380 ncr_irq=5 ncr_addr=0x350 ncr_5380=1
* for a port mapped NCR5380 board or
* modprobe g_NCR5380 ncr_irq=255 ncr_addr=0xc8000 ncr_53c400=1
* for a memory mapped NCR53C400 board with interrupts disabled.
*
* 255 should be specified for no or DMA interrupt, 254 to autoprobe for an
* IRQ line if overridden on the command line.
