[PATCH] rk3399: Add basic support for helios64

[Dennis Gilmore]

I have been working on an updated version, I have cleaned up the
config a lot as well as done some work to make the -u-boot.dtsi file
smaller https://pagure.io/u-boot/c/2472db2eff8ba0fb262a0d0264aa9d9c7b3eca32?branch=helios64
is my current WIP patch, I have built it on top of updating the base
rk3399 dtsi files to the versions in Linux 5.13
https://pagure.io/u-boot/c/64980d20f7e728afd659d0cfce2127bbf9f2e5ee?branch=helios64

The helios64 dts file in my patch includes the patches I sent to the
Linux kernel https://patchwork.kernel.org/project/linux-rockchip/patch/20210701004043.18585-1-dgilmore@redhat.com/
