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

In the Linux kernel, the following vulnerability has been resolved:

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

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.
