drm/amd/display: merge dc_link.h into dc.h and dc_types.h

[why]
Remove the need to include dc_link.h separately. dc.h should contain
everything needed on DM side.

[How]
Merge dc_link.h into dc.h and dc_types.h so DM only needs to include
dc.h to use all link public functions.

drm/amd/display: remove audio mute control in hpo dp

VPG doesn't have the ability to mute audio output by sending all 0s in
audio SDP. The existing implemention is disabling audio SDP instead.
This is same as what dp_audio_enable does. Since it is no longer
referenced by any callers, we decided to remove this interface for
simplicity.

drm/amd/display: polling vid stream status in hpo dp blank

[why]
vid stream control is double bufferred, if we don't wait for video
stream enable set to 0, we may get temporary image corruption
showing on the stream when setting PIXEL_TO_SYMBOL_FIFO_ENABLE to 0.

drm/amd/display: Add Missing HPO Stream Encoder Function Hook

[Why]
configure_dp_hpo_throttled_vcp_size() was missing promotion before, but it was covered by
not calling the missing function hook in the old interface hpo_dp_link_encoder->funcs.

Recent refactor replaces with new caller link_hwss->set_throttled_vcp_size
which needs that hook, and that causes null ptr hang.

drm/amd/display: Fix issue with dynamic bpp change for DCN3x

Why:
Screen sometimes would have artifacts or blink once at the time when bpp
is dynamically changed.

How:
1. Changed to update PPS infopacket in frame mode instead of immediate mode
since other updates for bpp change are double-buffered.
2. Changed double-buffering enablement programming for DCN30 as advised by
ASIC team
