Subject: [PATCH v8 9/9] [DO NOT MERGE] ARM: sun8i: v3s: enable LCD panel of Lichee Pi Zero

A 480x272 QiaoDian QD43003C0-40-7LED panel is available from Lichee Pi.

This commit connects this panel to Lichee Pi Zero.

Lichee Pi also provides a 800x480 panel without accurate model number,
so do not merge this patch. It will finally come as device tree overlay.
