drm/amd/display: optimize dml2 pipe resource allocation order

Browse source

[why]
There could be cases that we are transition from MPC to ODM combine.
In this case if we map pipes before unmapping MPC pipes, we might
temporarly run out of pipes. The change reorders pipe resource
allocation. So we unmapping pipes before mapping new pipes.
