drm/amd/display: Underflow workaround by increasing SR exit latency

Browse source

[Why]
On 14us for exit latency time causes underflow for 8K monitor with HDR on.
Increasing the latency to 28us fixes the underflow.

[How]
Increase the latency to 28us. This workaround should be sufficient
before we figure out why SR exit so long.
