Niklas Ekström 945db7f785 Add driver that uses the SD card on SF2000 
The current SF2000 firmware doesn't have a FIFO for communicating with
the SD card. This limits the achieved performance. This is expected to
change soon.

spi-lib-sf2000

The SF2000 Amiga accelerator has an SD card connector whose pins are routed to its FPGA. The firmware for the FPGA contains a basic SPI controller, which is used to communicate with the SD card. This spi-lib-sf2000 library abstracts the SPI controller using the same API as the spi-lib for the Amiga Parallel Port to SPI Adapter. This way, the spisd.device driver can be compiled with the spi-lib-sf2000 to build a driver that works with an SD card connected to the SF2000.
