spi/spi_bfin_sport: new driver for a SPI bus via the Blackfin SPORT peripheral

The Blackfin SPORT peripheral is a pretty flexible device.  With enough
coaching, we can make it generate SPI compatible waveforms.  This is
desirable as the SPORT can run at much higher clock frequencies than the
dedicated on-chip SPI peripheral, and it can do full duplex DMA.  It also
opens up the possibility of multiple SPI buses in case someone wants to
dedicate a whole bus to a specific part that does not play well with
others.
