description:
Explicitly disable v3d, pixelvalve, and hvs for bcm283x at the moment.

When these devices or hdmi are enabled, firmware turns off GPU functionality of
VideoCore, expecting OS drivers handle it appropriately:

https://github.com/raspberrypi/firmware/issues/763

This breaks userland applications using /dev/vchiq, such as omxplayer.

XXX We need enable them back when we import vc4 drm driver.

Fix PR port-evbarm/52984 and
PR port-arm/53042.

OK jmcneill, skrll
