drm/amd/display: Don't lock phantom pipe on disabling
[Description]
- When disabling a phantom pipe, we first enable the phantom
OTG so the double buffer update can successfully take place
- However, want to avoid locking the phantom otherwise setting
DPG_EN=1 for the phantom pipe is blocked (without this we could
hit underflow due to phantom HUBP being blanked by default)
