[ Upstream commit 9bf3797796f570b34438235a6a537df85832bdad ]

On sunxi boards that use HDMI output, HDMI device probe keeps being
avoided indefinitely with these repeated messages in dmesg:

  platform 1ee0000.hdmi: probe deferral - supplier 1ef0000.hdmi-phy
    not ready

There's a fwnode_link being created with fw_devlink=on between hdmi
and hdmi-phy nodes, because both nodes have 'compatible' property set.

Fw_devlink code assumes that nodes that have compatible property
set will also have a device associated with them by some driver
eventually. This is not the case with the current sun8i-hdmi
driver.

fw_devlink isn't present in 5.4 or earlier. So technically this patch
isn't needed.

I'll drop it from <=5.4, thanks!
