Use the drm_panel_get_modes() function to get the modes.

This patch leave one test for the function pointer:
    panel->funcs->get_modes

This is used to check if the panel may have any modes.
There is no direct replacement.
We may be able to just check that drm_panel_get_modes() return > 0,
but as this is not the same functionality it is left for later.
