drm/amd/display: Program pipes for ODM when removing planes 

[WHY?]
Software state expects pipes to be configured for ODM, but due to the transition
occurring on a plane disable, the ODM enablement code is not run.

[HOW?]
Update ODM when removing a plane, and dynamic ODM is active. Also acquire pipe
lock when removing a plane.
