drm/amd/display: temp w/a for dGPU to enter idle optimizations
[Why&How]
vblank immediate disable currently does not work for all asics. On
DCN401, the vblank interrupts never stop coming, and hence we never
get a chance to trigger idle optimizations.
Add a workaround to enable immediate disable only on APUs for now. This
adds a 2-frame delay for triggering idle optimization, which is a
negligible overhead.

Fixes: e45b6716de4b ("drm/amd/display: use a more lax vblank enable policy for DCN35+")
