Add initial Raspberry Pi 3 support
RPI3 kernel config builds kernel compatible with latest upstream device tree and firmware: https://github.com/raspberrypi/firmware/tree/master/boot As of today it's 597c662a613df1144a6bc43e5f4505d83bd748ca Default console is PL01x, so pi3-disable-bt dt overlay should be configured in config.txt and stock U-Boot should be patched to use proper serial port. Yet unsupported: SMP, VCHIQ, RNG driver. RNG requires some work due to upstream device tree incompatibility. Multiple people contributed to this work over time: db@, loos@, manu@
