sm8550: fix input regressions

[bulzipke]

Summary

• This PR reverts changes from
  SM8550: Home key mapping for AYN button on Thor #2824
  thor: Split lid switch from gpio-keys #2909
  which caused issues with lid switch / duplicate controller detection.
• Additionally, it changes the AYN button to KEY_HOME so it can be recognized in RetroArch.

Testing

• Tested on Thor(SM8550).
• Verified that the LID sensor (fake suspend) behaves correctly and that duplicate controller detection is resolved.

Additional Context

• BTN_BACK button remains unrecognized in RetroArch, as there are no available slots in the DualSense mapping.

that will move the KEY_HOME event out of the DS5 controller (it will be on gpio-key device), so it will probably have other effects in standalones mappings

I think the issue is as reported there are two DS5 devices, probably because InputPlumber is creating a second device when it detect the seperate gpio-keys-lid

I'd say the issue is in 02-ayn-controller.yaml‎

I see, I didn't take standalones into account.
I'll revert the AYN button mapping back to F24.

Bulzipke! It's great to see you! I used your original Digimon VPet emulator along with the evolution trees you put out like 15 years ago. Maybe longer. I used to play with it on my OLD Android phone back wheb I just started Learning about all the cool things Android could do.

Hearing that really makes my day. It was such a special time for me, and I’m so glad to hear it brings back fond memories for you as well.

I'd like to add you on Discord, but your name isn't pulling up. Is it something different?
