From: Robin Murphy <robin.murphy@xxxxxxx> [ Upstream commit 74532de460ec664e5a725507d1b59aa9e4d40776 ] NanoPi R2S is headless, so rightly does not enable any of the display interface hardware, which currently provokes an obnoxious error in the boot log from the fake DRM device failing to find anything to bind to. It probably isn't *too* hard to obviate the fake device shenanigans entirely with a bit of driver reshuffling, but for now let's just disable it here to shut up the spurious error.
