Saravana Kannan 360609fc8b drm/sun4i: dw-hdmi: Make HDMI PHY into a platform device 
[ Upstream commit 9bf3797796 ]

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.

This commit makes sun8i-hdmi-phy into a proper platform device
and fixes the display pipeline probe on sunxi boards that use HDMI.
