Sync the device tree files and device tree header files from upstream Linux kernel, as of 2020-01-08. The commit synced to in the sunxi repo 98d25b0b266d Merge branch 'sunxi/dt-for-5.6' into sunxi/for-next which is also part of next-20200108. Changes brought in include: - cleanup of pinmux node names - addition of Security ID, MBUS, CSI, crypto engine, video codec, pmu, and thermal sensor device nodes for both SoCs - addition of deinterlacing engine device node on H3 - cleanup of RTC device node and addition of its clocks - various board cleanups and improvements - removal of pinmux node for GPIO lines - cpufreq / DVFS - HDMI output - UART-based Bluetooth - audio codec - USB ports - new boards Most of the changes don't concern U-boot.
