tms380tr is used both by ISA and PCI drivers.  Enabling/disabling
DMA is done only for ISA ones (it's protected by if (dev->dma > 0) and
PCI ones leave it 0), but it's compiled unconditionally.  Which breaks
on platforms that don't have that ISA crap at all, but support PCI just
fine.  Code in question placed under ifdef CONFIG_ISA.
