The legacy SPI API was turned back on for the Adafruit Feather M0
Basic Proto when the SAM0 SoC was switched to using DTS for SPI. This
commit turns it back off.

Switch the SoC device tree to define a single entry per SERCOM instead
of one per mode.
Define a Device Tree binding for the SAM0 SPI and use it instead of
Kconfig for enabling / disabaling instances
Switch the Arduino Zero, Adafruit Feather M0 Basic Proto, and
Trinket M0 to use the new defintion.
Add the APA102 LED that's on the Trinket as a test.
