raspberrypi: update kernel, firmware, eeprom and userland

[mweinelt]

Motivation for this change

The kernel went from 5.4 to 5.10, I'm still building things and have not tested everything yet.

If someone beats me to it that is totally fine.

Things done

• Tested using sandboxing (nix.useSandbox on NixOS, or option sandbox in nix.conf on non-NixOS linux)
• Built on platform(s)
  • NixOS
  • macOS
  • other Linux distributions
• Tested via one or more NixOS test(s) if existing and applicable for the change (look inside nixos/tests)
• Tested compilation of all pkgs that depend on this change using nix-shell -p nixpkgs-review --run "nixpkgs-review wip"
• Tested execution of all binary files (usually in ./result/bin/)
• Determined the impact on package closure size (by running nix path-info -S before and after)
• Ensured that relevant documentation is up to date
• Fits CONTRIBUTING.md.

The kernel currently fails to build:

I'm disabling DRM_AST now and retrying.

Builds for me, still untested.
