Subject: [PATCH 02/12] ARM: dts: imx6qdl: rename ipu client nodes

To allow for IPU client devices that are composed of more than one
port for input and output (SMFC and IC), change the nodes from being
a single port node to nodes that can contain multiple ports. Rename
the nodes to use the following format: "ipu<id>_<subunit>".

The IPUv3 driver will then need to lookup the client nodes by name
rather than by port id.
