Leo Li 318917e1d8 drm/amd/display: Increase DCN35 SR enter/exit latency 
[Why & How]

On Framework laptops with DDR5 modules, underflow can be observed.
It's unclear why it only occurs on specific desktop contents. However,
increasing enter/exit latencies by 3us seems to resolve it.

Closes: https://gitlab.freedesktop.org/drm/amd/-/issues/4463
