Mike Frysinger 11d6f59951 Blackfin SPI Driver: get dma working for SPI flashes
When using a BF533-STAMP here with a W25X10 SPI flash.  It works fine when
enable_dma is disabled, but doesn't work at all when turning DMA on.  We
get just 0xff bytes back when trying to read the device.

Change the code around so that it programs the SPI first and then enables
DMA, it seems to work a lot better ...
