OF graph endpoint connections must be bidirectional and dtc will now
warn if they are not. i.MX7 based DTs have an error and generate
warnings:

Warning (graph_endpoint): /replicator/ports/port@0/endpoint: graph connection to node '/soc/tpiu@30087000/port/endpoint' is not bidirectional
Warning (graph_endpoint): /soc/tpiu@30087000/port/endpoint: graph connection to node '/replicator/ports/port@1/endpoint' is not bidirectional

This appears to be a copy-n-paste error and the TPIU input should be
connected to replicator port 0 instead of port 1.

Single child nodes in OF graph don't need an address and now dtc will
warn about this:

Warning (graph_child_address): /soc/aips@50000000/ldb@53fa8008/lvds-channel@0: graph node has single child node 'port@0', #address-cells/#size-cells are not necessary

Since the LDB should always have an output port, fix the warning by
adding the output port, 2, to the DT.
