Bug 1961646: Fix s2idle on AMD platforms without proper fw support

drm/amd: avoid suspend on dGPUs w/ s2idle support when runtime PM enabled

BugLink: https://bugs.launchpad.net/bugs/1961646

dGPUs connected to Intel systems configured for suspend to idle
will not have the power rails cut at suspend and resetting the GPU
may lead to problematic behaviors.

drm/amd: Only run s3 or s0ix if system is configured properly

BugLink: https://bugs.launchpad.net/bugs/1961646

This will cause misconfigured systems to not run the GPU suspend
routines.

* In APUs that are properly configured system will go into s2idle.
* In APUs that are intended to be S3 but user selects
  s2idle the GPU will stay fully powered for the suspend.
* In APUs that are intended to be s2idle and system misconfigured
  the GPU will stay fully powered for the suspend.
* In systems that are intended to be s2idle, but AMD dGPU is also
  present, the dGPU will go through S3

drm/amd: Warn users about potential s0ix problems

BugLink: https://bugs.launchpad.net/bugs/1961646

On some OEM setups users can configure the BIOS for S3 or S2idle.
When configured to S3 users can still choose 's2idle' in the kernel by
using `/sys/power/mem_sleep`. Before commit 6dc8265f9803 ("drm/amdgpu:
always reset the asic in suspend (v2)"), the GPU would crash. Now when
configured this way, the system should resume but will use more power.

As such, adjust the `amdpu_acpi_is_s0ix function` to warn users about
potential power consumption issues during their first attempt at
suspending.
