drm/amd/display: Update vactive margin and max vblank for fpo + vactive
[Description]
- Some 1920x1080@60hz displays have VBLANK time > 600us which we
still want to accept for FPO + Vactive configs based on testing
- Increase max VBLANK time to 1000us to allow these configs
for FPO + Vactive
- Increase minimum vactive switch margin for FPO + Vactive to 200us
- Based on testing, 1920x1080@120hz can have a switch margin
of ~160us which requires significantly longer FPO stretch
margin (5ms) which we don't want to accept for now
- Also move margins into debug option
