Julia 3966f67746 zephyr/machine_spi: Add support for hardware SPI. ...

Adds support for hardware SPI to the zephyr port.  Consistent with other
ports, such as rp2 and stm32, we only implement the SPI protocol functions
(init and transfer).  Explicit sck/mosi/miso selection is not supported
and new SPI instances are initialized with default values.
