Adds dts spi bindings for the kinetis dspi controller, and updates the
k64, kw2xd, kw40z, kw41z dts nodes accordingly.
Updates the dts interrupt priorities to match the board defconfigs
(e.g., boards/arm/frdm_k64f/Kconfig.defconfig)
For k64, fixes an error in the spi1 interrupt number and adds a third
instance (spi2).

Now that we can generate gpio info from dts lets add optional support
fot the cs-gpios property in the bus controller node. This matches the
binding spec from Linux on how cs-gpios are handled.

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.
