drm/panel: simple: Allow DSI panels to provide mode flags

In order to differentiate between the different video modes (burst vs.
non-burst, sync pulses vs. sync events) supported by peripherals, pass
the flags that specify this mode in the panel description to the DSI
peripheral device when probed.
