drm/amd: Don't reset dGPUs if the system is going to s2idle

Browse Source 
An A+A configuration on ASUS ROG Strix G513QY proves that the ASIC
reset for handling aborted suspend can't work with s2idle.

This functionality was introduced in commit daf8de0874 ("drm/amdgpu:
always reset the asic in suspend (v2)").  A few other commits have
gone on top of the ASIC reset, but this still doesn't work on the A+A
configuration in s2idle.

Avoid doing the reset on dGPUs specifically when using s2idle.

Fixes: daf8de0874 ("drm/amdgpu: always reset the asic in suspend (v2)")
