boards: arm: arduino_portenta_h7: Add support for Arduino Portenta H7
This commit adds support for the Arduino Portenta H7 board. The board functionallity has been verified by running following samples: - hello_world on m7 core - usb/console on m7 core - blinky on m4 core Signed-off-by: Benjamin Björnsson <[email protected]>
