The Allwinner H616 has a display pipeline similar to other Allwinner
devices, specifically the A10, but using a newer display engine
revision (DE33).

Not all output pins are exposed on all package variants, for example
only the H700 and T507 have LCD pins exposed, but all variants support
HDMI output. However on the die these are connected to a display engine
via a TCON TOP and one or more timing controllers (TCONs).

HDMI output support is not provided in this series (but will be in a
subsequent patch) so for now note this within the relevant node to
prevent a DT compiler error.

Add TCON nodes for the TOP, and the LCD and TV timing controllers. The
timing controllers are compatible with the existing R40 driver.
