This is not right. The mikrobus socket is more than just SPI which was
already pointed out. I also sketched out how I think it needs to look.
Maybe it ends up looking a bit different, but fundamentally, how you
remap I2C, SPI, GPIO, PWM, etc. thru a connector in order to have
overlays which are independent of the base platform has to be solved.
So far, we have done interrupts and GPIOs.
