spi: SuperH SPI using SCI
Add support for SPI over SCI pins. SCI is a very simple serial controller block that can be found on older SuperH processors. In theory it is possible to use the SCI hardware block in syncronous mode, but this version of the driver simply hooks up the bit banging code on the SCI pins.
