boards: stm32: Set arduino gpio connector on nucleo 64 pins boards Apply same scheme for all nucleo_64 pins boards: -provide a separate arduino connector dtsi file -provide complete gpio map -update board.yaml vs arduino support (i2c, spi and gpio) Signed-off-by: Erwan Gouriou <erwan.gouriou@linaro.org>

#gpio-cells = <2>;
devicetree: tree-wide: add nexus map properties for arduino headers We need to be able to specify GPIO flags in devicetree without that preventing translation from the Arduino specifier to the host GPIO specifier. Set up to ignore the low 6 bits of the flags field when matching the child specifier, and to copy those bits to the parent specifier. Signed-off-by: Peter Bigot <peter.bigot@nordicsemi.no>
