Rock5B Support

[lovesegfault]

I have one and am happy to help test, I think it should be pretty similar (identical?) to the Rock5A with Collabora sources

There are already other projects that support rock5b, I think you can just try it:

I wonder if nanopi R6S is worth supporting

@grsmith-projects You may want to take a look at this: https://nixos.wiki/wiki/NixOS_on_ARM/NanoPi-R6C
which recommends using UEFI firmware edk2 to start NixOS, and it supports R6S/Rock5B too.

I haven't tried yet, but it does not require any customization of NixOS, it can be started directly using NixOS's official ISO for aarch64, which sounds very attractive.

FYI, I've just added UEFI support for rk3588, it makes it much easier to add any new SBC, so I plan to add support for more RK3588/RK3588s based SBCs next, including Rock 5B.
