Here are some device tree updates to improve sound output on RK3576 boards.
The first two patches fix analog audio output on FriendlyElec NanoPi M5, as it doesn't work with the current device tree.
The third one is purely cosmetic, to present a more user-friendly sound card name to the userspace on NanoPi M5.
The rest add new functionality: HDMI sound output on three boards that didn't enable it, and analog sound on RK3576 EVB1.
