drm: bridge: adv7511: Fix ADV7535 HPD enablement

[ Upstream commit 3dbc84a595d17f64f14fcea00120d31e33e98880 ]

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.
