Steam Deck OLED - Wireless Xbox Controller stops waking system after it's been rebooted

Your system information

• Steam client version: 1710458266
• SteamOS version: 3.5.17
• Opted into Steam client beta?: No
• Opted into SteamOS beta?: No
• Have you checked for updates in Settings > System?: Yes

Please describe your issue in as much detail as possible:

After the Steam Deck has been restarted, a paired Xbox controller will no longer wake the device over Bluetooth without being unpaired and then paired again in the Bluetooth settings menu. It will then work properly and wake the device until the system is restarted again. The controller must be repaired every time the Steam Deck is restarted.

I've tested this issue and replicated it with two recent Xbox controllers (both patched with their latest firmware). However, the issue does not occur with an 8bitdo SN30Pro controller paired to the device, which will continue to wake the device after reboot.

I've tested this docked in the official Steam Deck Dock and undocked, but in the actual use case, it's been docked every time (since I don't normally use a controller undocked).

Steps for reproducing this issue:

1. Pair an Xbox controller to the Steam Deck OLED
2. Put the device in sleep mode. The controller's guide button should wake it.
3. Reboot the Steam Deck
4. Put the Steam Deck into sleep mode
5. The Xbox Controller's guide button will no longer wake the Steam Deck until it is unpaired and repaired.

I have the same problem since the begining with Steam Deck Oled and Xbox Series X controller. Always on stable branch.
