NAK.
DSI panels are children of the DSI device tree node with the reg = <0>; address.
This is the convention used by other platforms too (see e.g.
arch/arm64/boot/dts/freescale/imx8mq-evk.dts).

With the DSI split link it is possible to attach two panels to a
single DSI host, so addresses are necessary.
