drm: bridge: adv7511: Fix ADV7535 HPD enablement
Existing HPD enablement logic is not compatible with ADV7535
bridge, thus any runtime plug-in of HDMI cable is not working
on these bridge designs.
Unlike other ADV7511 family of bridges, the ADV7535 require
HPD_OVERRIDE bit to set and reset for proper handling of HPD
functionality.
Fix it.
