You'll now need
CONFIG_DRM_DP_HELPER=y

There was discussion about this last November but I guess nothing came of it?
https://lore.kernel.org/r/20211117062704.14671-1-rdunlap@infradead.org/
In there Arnd provided a proposed patch. If everyone likes that and it
fixes things then we can apply it...

Yep, apparently this was broken before. We recently moved these symbols
from CONFIG_DRM_KMS_HELPER behind CONFIG_DRM_DP_HELPER. We'd have to use
