MSM DRM driver already allows one to compile out the DP or DSI support.
Add support for disabling other features like MDP4/MDP5/DPU drivers or
direct HDMI output support.

<title>drm/display: Introduce a DRM display-helper module</title>

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/

Register logging was used during early stages of msm driver development
to compare upstream and downstream register traces. However the tool was
never updated to work with mdp5 hardware. Later it was dropped
completely when Rob imported freedreno tools into mesa. All this makes
DRM_MSM_REGISTER_LOGGING irrelevant now, so it can be dropped.

<title>drm/dp: Move DisplayPort helpers into separate helper module</title>

<id>urn:sha1:adb9d5a2cc77e8aefe98fe4c11656c5b7025c248</id>
<content type='text'>
Move DisplayPort functions into a separate module to reduce the size
of the KMS helpers. Select DRM_DP_HELPER for all users of the code. To
avoid naming conflicts, rename drm_dp_helper.c to drm_dp.c

This change can help to reduce the size of the kernel binary. Some
numbers from a x86-64 test build:

Before:
	drm_kms_helper.ko:	447480 bytes

After:
	drm_dp_helper.ko:	216632 bytes
	drm_kms_helper.ko:	239424 bytes

For early-boot graphics, generic DRM drivers, such as simpledrm,
require DRM KMS helpers to be built into the kernel. Generic helper
functions for DisplayPort take up a significant portion of DRM KMS
helper library. These functions are not used by generic drivers and
can be loaded as a module.

v3:
	* fix include statement in DRM selftests
v2:
	* move DP helper code into dp/ (Jani)
