The amdgpu_dm file contains most of the code that works as an interface
between DRM API and Display Core. We maintain all the plane operations
inside amdgpu_dm; this commit extracts the plane code to its specific
file named amdgpu_dm_plane. This commit does not introduce any
functional change to the functions; it only changes some static
functions to global and adds some minor adjustments related to the copy
from one place to another.
