snow: Remove remnants of partial SPI support
We started SPI development on the Snow platform, but then repurposed
some of the GPIOs to use for I2C arbitration. Now that we have Pit,
we'll never go back and finish SPI on Snow, so this code can be removed.
Remove the remaining dead code from Snow. This makes it easier to do the
GPIO alternate function refactoring.
