Non-PCI devices are responsible for checking device matches
themselves by overriding can_present_on_device on wsi_device
to take the non-blitting WSI path.

We can allow on-device presentation for both the display
controller, and any panthor node. The simplest way of
achieving that is allowing this for all devices with bus
type platform, as there's nothing else that has this
property.
