Douglas Anderson 0bd79f915c drm/bridge/synopsys: dw-hdmi: Fix unwedge crash when no pinctrl entries 
In commit 50f9495efe ("drm/bridge/synopsys: dw-hdmi: Add "unwedge"
for ddc bus") I stupidly used IS_ERR() to check for whether we have an
"unwedge" pinctrl state even though on most flows through the driver
the unwedge state will just be NULL.

Fix it so that we consistently use NULL for no unwedge state.

Fixes: 50f9495efe ("drm/bridge/synopsys: dw-hdmi: Add "unwedge" for ddc bus")
