Fix SPI startup on Teensy 4.1 #45

Opps, the changes I made to turn on DAC8586 Vref early (which requires using SPI) messed up SPI startup.

This change makes the 3 cases for Teensy 4.x separate, even though 2 of them are identical, so it's easy to see how SPI startup differs depending on which board we're targeting.

"DAC8586" ?
