[Nouveau] [PATCH v2 00/13] replace drm_detect_hdmi_monitor() with drm_display_info.is_hdmi

Changelog:
v2:
- no helper function
- A separate patch is made for amdgpu
- zte patch is removed because that driver no longer exists

[Why]
Copy&paste from Documentation/gpu/todo.rst 
==Replace drm_detect_hdmi_monitor() with drm_display_info.is_hdmi
---------------------------------------------------------------

Once EDID is parsed, the monitor HDMI support information is available through
drm_display_info.is_hdmi. Many drivers still call drm_detect_hdmi_monitor() to
retrieve the same information, which is less efficient.

Audit each individual driver calling drm_detect_hdmi_monitor() and switch to
drm_display_info.is_hdmi if applicable.
====
[How]
I did it in two steps:
- check that drm_display_info has a correct value.
- in that case, replace drm_detect_hdmi_monitor() with drm_display_info.is_hdmi

Almost all occurrences of drm_detect_hdmi_monitor() could be changed. Some
small inconsistencies have been solved.

[Nouveau] [PATCH v2 01/13] gpu/drm: make drm_add_edid_modes() consistent when updating connector->display_info

According to the documentation, drm_add_edid_modes
"... Also fills out the &drm_display_info structure and ELD in
@connector
with any information which can be derived from the edid."

drm_add_edid_modes accepts a struct edid *edid parameter which may have a
value or may be null. When it is not null, connector->display_info and
connector->eld are updated according to the edid. When edid=NULL, only
connector->eld is reset. Reset connector->display_info to be consistent
and accurate.

[Nouveau] [PATCH v2 02/13] drm/vc4: replace drm_detect_hdmi_monitor() with drm_display_info.is_hdmi

Once EDID is parsed, the monitor HDMI support information is available
through drm_display_info.is_hdmi. Use this value instead of calling
drm_detect_hdmi_monitor() to avoid a second parse.

This is a TODO task in Documentation/gpu/todo.rst

[Nouveau] [PATCH v2 03/13] drm/radeon: replace drm_detect_hdmi_monitor() with drm_display_info.is_hdmi

Once EDID is parsed, the monitor HDMI support information is available
through drm_display_info.is_hdmi. Retriving the same information is less
efficient. Change to drm_display_info.is_hdmi

This is a TODO task in Documentation/gpu/todo.rst

Also, correct an inacurracy or bug in
radeon_connector_get_edid()/radeon_connector_free_edid(). Two variables
have EDID data:
- struct radeon_connector.edid
- struct drm_connector.edid_blob_ptr
The second is updated by calling drm_connector_update_edid_property() or
drm_get_edid() - which internally calls drm_connector_update_edid_property().
drm_display_info.is_hdmi is updated when this function is called.
radeon_connector_get_edid() calls drm_get_edid() to update
drm_connector.edid_blob_ptr/drm_display_info only in some cases. Change it
to be always up to date, so drm_display_info is always correct.
As counterpart, reset these values in radeon_connector_free_edid().

This second change is necessary for the previous one to work properly.

[Nouveau] [PATCH v2 08/13] drm/sun4i: replace drm_detect_hdmi_monitor() with drm_display_info.is_hdmi

Once EDID is parsed, the monitor HDMI support information is available
through drm_display_info.is_hdmi. Retriving the same information with
drm_detect_hdmi_monitor() is less efficient. Change to
drm_display_info.is_hdmi
