The amdgpu_dm_plane.h functions didn't have names that indicated where
they were declared.
To better filter results in debug tools like ftrace, prefix these
functions with 'amdgpu_dm_plane_'.
Note that we may want to make this same change in other files like
amdgpu_dm_crtc.h.

Add details about color correction capabilities and explain a bit about
differences between DC hw generations and also how they are mapped
between DRM and DC interface. Two schemas for DCN 2.0 and 3.0 (converted
to svg from the original png) is included to illustrate it. They were
obtained from a discussion[1] in the amd-gfx mailing list.

In the DC driver, we have multiple acronyms that are not obvious most of
the time; the same idea is valid for amdgpu. This commit introduces a DC
and amdgpu glossary in order to make it easier to navigate through our
driver.
Changes since V3:
- Yann: Add new acronyms to amdgpu glossary
- Daniel: Add link between dc and amdgpu glossary
Changes since V2:
- Add MMHUB
Changes since V1:
- Yann: Divide glossary based on driver context.
- Alex: Make terms more consistent and update CPLIB
- Add new acronyms to the glossary
