arm: dts: sunxi: h5: Update DT files

Update the H5 DT files from the Linux 5.12 release.

The changes don't affect U-Boot at all, but fix Gigabit Ethernet when
this DT is passed on to the Linux kernel. It also introduces DVFS.

This also updates the shared sunxi-h3-h5.dtsi, but that only adds nodes
that are of no concern to U-Boot.
