drm/mediatek: Make eDP panel as the first connected connector
[Why]
Some userspaces assume that the first connected connector is the "main"
display, which supposed to display, for example, the login screen.
For laptops, this should be the internal connector.
[How]
This patch calls drm_helper_move_panel_connectors_to_head() right before
crtc creation to ensure internal connectors are at the top of the
connector list.
Tested by ensuring the internal panels are at the top of the connector
list via modetest -c.
This patch does to mediatek what the following patch
https://www.spinics.net/lists/stable/msg590605.html
did for qualcomm.
