dts: atmel sam: Add pinctrl support for SAM SPI
Add pinctl support for the SAM SPI device. We update the SPI
binding to have pinctrl-0 bindings that are expected to have
at least phandles for MISO, MOSI, and SPCK, but might also have
various chip selects as well.
The pinctrl nodes will have an 'atmel,pins' property that describes the
GPIO port, pin and periphal configuration for that pin.
We update sam*-pinctrl.dtsi files with all the various pin ctrl
configuration operations supported by the given SoC family. These
files are based on data extracted from the Atmel ASF HAL
(in include/sam<FAMILY>/pio/*.h).
