hook-functions: dep_add_modules: Properly include panel drivers

Browse Source 
With MODULES=dep, we try to walk the /sys/devices/platform/edp-panel
device to include panel drivers because they are needed get a display
output on some devices. This is a bit wrong, because the "edp-panel"
here is the name of a device-tree node that is not necessarily a panel.

Instead, walk the devices bound under the panel drivers for modules to
add to initramfs. Check not only for panel-edp, but panel-simple and
those available over dp-aux bus as well.
