46676547d9 spi: add SPI_DELAY decl 
AVR chips often run at less than z80's system clock. This means that
our SPI relay needs to have its own clock to properly communicate
with it. This means that the delay between OUT and IN can't be
hardcoded to 2 NOPs anymore. It needs to be configurable.

f09aa0603c rc2014: separate SPI relay and SDC drivers 
My intention is to reuse the SPI relay to program AVR MCUs from a
RC2014.
