Add it as suggested in the patch ("dt-bindings: drm/bridge: ti-sn65dsi86: Document no-hpd"). NOTE: this patch isn't expected to have any effect but just keeps us cleaner for the future. Currently the driver in Linux just assumes that nobody has HPD hooked up. This change allows us to later implement HPD support in the driver without messing up sdm845-cheza.
