hwids: add Radxa Orion O6

[ArminiusTux]

Although this board has received a working ACPI hardware disclosure, a device tree fallback surely would not hurt.

device tree sources (sky1-orion-o6.dts):

• Penguin-dictator's vault

• Sky1-community

• Armbian's nest

wouldn't this override ACPI by default? which one should be preferred when ACPI is available (and usable) too?

Good question, surely this BIOS switch (ACPI off) would make it work.

If the desired operating mode (ACPI on) however, requires the OS to offer a dual-track (DTB & ACPI) support is beyond me.
Maybe @Entrpi, who maintains this Sky1-Linux subrepo, can answer this.

In the Sky1 testing, I've generally left ACPI on in UEFI but specified acpi=off to the kernel.

If I've understood the very recently added https://github.com/ubuntu/stubble#device-tree-selection correctly shouldn't this PR be unnecessary? Only would need to include the dtb via --devicetree-auto=... if stubble is wanted to override the firmware-provided one (I assume it does that?) when it's in Device Tree mode as shown in the above picture, and while it's in ACPI mode the expected thing happens with that
