drm/panel-simple: fix connector type for DataImage SCF0700C48GGU18 panel

commit 6ab3d4353b upstream.

The connector type for the DataImage SCF0700C48GGU18 panel is missing and
devm_drm_panel_bridge_add() requires connector type to be set. This leads
to a warning and a backtrace in the kernel log and panel does not work:
"
WARNING: CPU: 3 PID: 38 at drivers/gpu/drm/bridge/panel.c:379 devm_drm_of_get_bridge+0xac/0xb8
"
The warning is triggered by a check for valid connector type in
devm_drm_panel_bridge_add(). If there is no valid connector type
set for a panel, the warning is printed and panel is not added.
Fill in the missing connector type to fix the warning and make
the panel operational once again.
