drm/bridge/synopsys: dw-hdmi: Fix unwedge crash when no pinctrl entries
In commit 50f9495efe30 ("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.
