drm/amd/display: update nv1x stutter latencies

Linux kernel mirror (for testing) git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

kernel os linux

[why]
Recent characterization shows increased stutter latencies on some SKUs,
leading to underflow.

[how]
Update SOC params to account for this worst case latency.
