drm/amdgpu/display: Add amdgpu_display.c documentation

Add kernel-doc references for amdgpu_display.c to the display manager
documentation. This pulls in documentation for display core functions
like the hotplug work handler, and the adaptive backlight modulation
property.

The :internal: directive automatically includes all function documentation,
while the explicit :doc: directive captures the property documentation that
:internal: doesn't pull in.
