The initial U-Boot F1C100s port was based on the mainline kernel DT files, which were quite basic and were missing the essential MMC and SPI peripherals. While we could work around this in the SPL by hardcoding the required information, this left U-Boot proper without SD card or SPI flash support, so actual loading would require FEL boot. Now the missing DT bits have been submitted and accepted in the kernel tree, so lets sync back those files into U-Boot to enable MMC and SPI, plus benefit from some fixes. This is a verbatim copy of the .dts and .dtsi file from linux-sunxi/dt-for-5.19[1], which have been part of linux-next for a while as well.
