[PATCH] 2.5.24: generic ATA PCI auto-dma tuning (2/5)

        - add udma_generic_setup() to pcidma.c, which
                  - equals functionality of driver specific udma_setup()
                  and config_chipset_for_dma()
                - makes use of ch->modes_map, ch->no_atapi_autodma
                  and ch->speedproc()/tuneproc()
                - auto-tunes PIO only if we failed to enable DMA
                  (PIO auto-tuning is already handled by ch->tuneproc()
                  call in probe.c, it is controlled separetly of autodma)

        - convert aec62xx.c, amd74xx.c, cmd64x.c, hpt34x.c, piix.c,
                  serverworks.c, sis5513.c and via82cxxx.c to new scheme

        - this has nice side effect of teaching aec, amd, piix and via
          drivers using DMA blacklist/whitelist
