Revert "drm/panel: simple: Add missing connector type and pixel format for AUO T215HVN01"

This reverts commit dbdc8289 which is
commit 7a675a8fa598edb29a664a91adb80f0340649f6f upstream.

It breaks the build as it depends on an ABI change that was reverted
from the tree in older versions.  If this is needed in the future, it
can be brought back in an ABI-safe way.
