While taking a glance at the novatek-nt36672e driver I stumbled upon a call to unregister the DSI device for the panel, although it was not the panel driver that registered the device. Remove this call and a similar call from the visionox-rm69299 driver. While we are at it, also optimize regulator API calls in these two drivers and in the novatek-nt36672a driver.
