drm: kirin: Fix drm_of_find_panel_or_bridge conversion

This fixes a regression introduced by ebc944613567 ("drm:
convert drivers to use drm_of_find_panel_or_bridge") that was
recently merged, causing HDMI output to not work.

For the kirin driver, the port value should be 1 instead of 0,
so this oneline patch fixes it and gets graphics working again.
