ARM: ux500: convert Snowball SPI pin reference
The SPI0 block is not at all connected to the AB8500 on the Snowball: it is connected to the external header. These pins on the header may also be used for GPIO, but let's assume that SPI is a probable usecase on the Snowball and mux in the SPI block and use these for SPI.
