Matteo Golin e96fb6b118 arch/bcm2711, boards/raspberry-pi-4b: Add preliminary support for the BCM2711 and Raspberry Pi 4B.
Includes a Mini-UART NSH console for the 4B, tested on the 4GB RAM
model. Part of an I2C driver which can only read, boiler-plate for a SPI
driver, and a GPIO driver with limited pins. Some tools are present for
automatically fetching the boot files and creating the `config.txt` file
based on selected Kconfig options.
