get_modes
Make the dp/hdmi_audio_* callback maintain the same parameter order as
get_modes and edid_read: first the bridge, then the connector.

Now as the msm_dp_catalog module became nearly empty, drop it, accessing
registers directly from the corresponding submodules.

The MSM DisplayPort driver implements several HDMI codec functions
in the driver, e.g. it manually manages HDMI codec device registration,
returning ELD and plugged_cb support. In order to reduce code
duplication reuse drm_hdmi_audio_* helpers and drm_bridge_connector
integration.

The dp_audio module doesn't make any use of the passed DP panel
instance. Drop the argument.

For historical reasons a lot of symbols in the MSM DisplayPort driver
used the generic dp_ prefix. Perform a mass-rename of those symbols to
use msm_dp prefix.
Basically this is a result of the following script:
sed drivers/gpu/drm/msm/dp/* -i -e 's/\<dp_/msm_dp_/g'
sed drivers/gpu/drm/msm/dp/* -i -e 's/"msm_dp_/"dp_/g'
sed drivers/gpu/drm/msm/dp/* -i -e 's/msm_\(dp_sdp_header\|dp_sdp\)\>/\1/g'
Yes, this also results in renaming of several struct fields in addition
to renaming the structs and functions, but I think the simple solution
is better than the more complex one.

while binding the code always registers a audio driver, however there
is no corresponding unregistration done in unbind. This leads to multiple
redundant audio platform devices if dp_display_bind and dp_display_unbind
happens multiple times during startup. On X13s platform this resulted in
6 to 9 audio codec device instead of just 3 codec devices for 3 dp ports.
Fix this by unregistering codecs on unbind.

Introduce audio support for Display Port on MSM chipsets.
This change integrates DP audio sub-module with the main
Display Port platform driver.
In addition, this change leverages hdmi_codec_ops to expose
the operations to the audio driver.
Changes in v2: fix up a compilation issue on drm-next branch
Changes in v3: none
Changes in v4: none
Changes in v5: none
Changes in v6: rebase on top of latest patchset of dependency
