Reworked sam_gmac driver to get pin ctrl/mux configuration information
from the device tree instead of via Kconfig and defines in soc_pinmap.h
We remove defines from soc_pinmap.h that are no longer needed due to
getting all that information from devicetree.

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).

Add pinctl support for the SAM TWI and TWIHS I2C devices. We update
the TWI and TWIHS I2C bindings to have pinctrl-0 bindings that are
expected to have 2 phandles to the TWCK & TWD pinctrl nodes.
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

Add pinctl support for the SAM UART and SAM USART devices. We update
the UART and USART bindings to have pinctrl-0 bindings that are expected
to have 2 phandles to the RX & TX pinctrl nodes.
The pinctrl nodes will have an 'atmel,pins' property that describes the
GPIO port, pin and periphal configuration for that pin.

configuration operations supported by the given SoC family. These
