drm/amd/display: enable audio on DP seamless boot
[Why]
Some external displays with DP can use seamless boot, but their audio endpoints are
only enabled after hotplug.
On boot, these displays inherit UEFI timings without properly initializing audio.
[How]
Enable display audio when seamless booting with an external monitor over DP.
