drm/display: Select DP helper for DRM_DP_AUX_CHARDEV and DRM_DP_CEC 
The DRM_DP_AUX_CHARDEV and DRM_DP_CEC Kconfig symbols enable code that use
DP helper functions, that are only present if CONFIG_DRM_DISPLAY_DP_HELPER
is also enabled.

But these don't select the DRM_DISPLAY_DP_HELPER symbol, meaning that it
is possible to enable any of them without CONFIG_DRM_DISPLAY_DP_HELPER.

That will lead to the following linking errors with the mentioned config:

make: *** [Makefile:1749: modules] Error 2

Besides making these symbols to select CONFIG_DRM_DISPLAY_DP_HELPER, make
them to depend on DRM_DISPLAY_HELPER, since can't be enabled without it.

Note: It seems this has been an issue for a long time but was made easier
to reproduce after the commit 1e0f66420b ("drm/display: Introduce a DRM
display-helper module"). Adding a Fixes: tag just to make sure that this
fix will be picked for stable once the mentioned change also lands there.

1e6b8d5df0 drm/dp_mst: Lower down debug info level when receive NAK 
[Why]
It's reasonable that we receive NAK while doing DP_REMOTE_DPCD_READ.
Downstream device might reply NAK with the reason and source should
react accordingly.

e.g.
1. When downstream device can't handle corresponding message in time,
it then replies NAK as reason been set as DEFER.
2. When multi-function branch-sink device doesn't enumerate virtual
DP peer devices for those multi-function down facing ports. Without
virtual DPCD, branch device might reply NAK with reason as BAD_PARAM
indicating this port can't do aux DPCD read.

It's expected result. Not an error.

[How]
Use drm_dbg_kms() to replace drm_err() when receive NAK.

Changes since v1:
* drm_dp_mst_topology.c file path changed. Folder was rename from
 'dp' to 'display'

To avoid the proliferation of Kconfig options, SCDC is part of DRM's

4fc8cb47fc drm/display: Move HDMI helpers into display-helper module 
Move DRM's HMDI helpers into the display/ subdirectoy and add it
to DRM's display helpers. Update all affected drivers. No functional
changes.

The HDMI helpers were implemented in the EDID and connector code, but
are actually unrelated. With the move to the display-helper library, we
can remove the dependency on drm_edid.{c,h} in some driver's HDMI source
files.

Several of the HDMI helpers remain in EDID code because both share parts
of their implementation internally. With better refractoring of the EDID
code, those HDMI helpers could be moved into the display-helper library
as well.

1e0f66420b drm/display: Introduce a DRM display-helper module 
Replace the DP-helper module with a display-helper module. The
support for DisplayPort becomes an internal option that drivers
have to select. Update all related Kconfig and Makefile rules.

Besides the existing code for DisplayPort, the new module will
contain helpers for other video-output standards, such as HDMI.
Drivers will have to select their required video-output helpers.

Linking all display-related code into a single module avoids the
proliferation of small kernel modules.

The module parameters drm_dp_cec_unregister_delay, dp_aux_i2c_speed_khz,
and dp_aux_i2c_transfer_size are moving from the drm_dp_helper namespace
to drm_display_helper.

v2:
	* mention module parameters in commit message (Javier)
	* distiguish between display module and DP support in Kconfig
	* update Makefile rules for DP helpers
	* move Kconfig rules into separate file under display/
