Add -u-boot.dtsi files to keep the current U-Boot behaviour: - add u-boot,dm-pre-reloc where required - disable watchdog - set uart clock frequency - add gpio bank-name properties where appropriate: - make qspi work (add alias for spi0, fix compatible for flash) - enable usb (status okay, add alias for udc0) Adapt board dts files that are not in Linux to keep their old behaviour. Change licenses to SPDX. (Patman warnings/errors are in 1:1 copied files from Linux) Signed-off-by: Simon Goldschmidt <simon.k.r.goldschmidt@gmail.com>
