[TC] defxx: TURBOchannel support
This is a set of changes to add TURBOchannel support to the defxx driver. As at this point the EISA support in the driver has become the only not having been converted to the driver model, I took the opportunity to convert it as well. Plus support for MMIO in addition to PIO operation as TURBOchannel requires it anyway. Signed-off-by: Maciej W. Rozycki <macro@linux-mips.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Acked-by: Jeff Garzik <jeff@garzik.org> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
