Fix screen rotation on Zeenix handhelds

[Raxcoms]

Describe the bug

Recently a company called Tectoy re-released a couple of Ayn Loki devices under the brand "Zeenix"

I have a unit of the new Loki Max called Zeenix Pro
The device still has the same specs as the og Loki Max

It has a native vertical screen with the top facing the right side of the handheld
In game mode the screen is upside down

I believe every loki max tweak like min/max tdp, button that opens quick settings, etc. probably applies to this unit as well.

What did you expect to happen?

Display to be in the right orientation

Output of rpm-ostree status

Hardware

Extra information or context

No response

could you let me know the output of these two when you run in a terminal on your device?

cat /sys/devices/virtual/dmi/id/product_name

/usr/libexec/hwsupport/sysid

[Raxcoms]

The output for cat /sys/devices/virtual/dmi/id/product_name is "Zeenix Pro"
I had it ran before as the bug report template prompted for it

From checking dmi information it also listed "Tectoy" as the manufacturer

Unfortunately my unit ended up having a hardware defect and I ended up returning it, so I can't run the other command

Before I sent it back I fixed the upside down screen in game mode by running the following line I found on a legion go thread

sudo rpm-ostree kargs --append-if-missing video=eDP-1:panel_orientation=left_side_up

In case this helps in any way
