This series adds pdata quirks and other changes required to make vpif
work on the da850-evm board.
v1 -> v2:
- added patch 3/3
- specified the purpose of port@0 and port@1 nodes
v2 -> v3:
- removed patch 3/3 - it may take some more time to determine the
correct solution for enable-gpios, so I decided to respin the
series without it and send it later as a follow-up
- added Rob Herring's acks

The examples have been copied from the DT with whitespace errors. Fix
them.

This makes the example more or less correspond with the da850-evm
hardware setup.
