So remove the hotplug pinctrl setting and enable the force-hpd option, to allow them to find the display too. While on speedy boards, the hotplug pin is connected, judging by comments in a chromeos change it seems the "panels HPD voltage is too low to be detected", so it also needs the forced hotplug, as we of course also know that a display is connected.
