Navi 21 GFX hangs since "drm/amd/amdgpu: add pipe1 hardware support"

Brief summary of the problem:

GFX hangs occur shortly after logging into a GNOME Wayland session (which makes use of the EGL_IMG_context_priority extension to get a high priority context for gnome-shell).

Bisected to agd5f/linux@4c763180.

I tried amdgpu.async_gfx_ring=0 on the kernel command line as a workaround, but that resulted in the amdgpu driver failing to initialize successfully at all.

Hardware description:

• GPU: AMD Navi 21 GL-XL [Radeon PRO W6800]

System information:

• Kernel version: 5.19.0+
• Custom kernel: drm-next-2022-08-03 tag merged on top of linux-5.19.y branch
• Mesa 22.2.0-rc1 or newer

How to reproduce the issue:

1. Boot kernel which has the bisected commit
2. Log into GNOME Wayland session
3. Run Steam in Big Picture mode

The GFX hang occurs within a few seconds of the Steam Big Picture mode starting up.
