Where do these two come from? They fail to validate with commit
cfe34bb7a770c5d8 ("dt-bindings: drm: bridge: adi,adv7511.txt: convert
to yaml").
I can't find where it is used in the driver, nor in the driver history.
Perhaps it was set in some obscure place, and is no longer needed since
commit 67793bd3b3948dc8 ("drm/bridge: adv7511: Fix low refresh rate
selection")?
