Add platform_set_drvdata in all designware based drivers to store the
private data structure of the driver so that dev_set_drvdata can be
used to get back private data pointer in add_pcie_port/host_init.
This is in preparation for splitting struct pcie_port into core and
host only structures. After the split pcie_port will not be part of
the driver's private data structure and *container_of* used now
to get the private data pointer cannot be used.

This is an example of a change that could be merged with another patch that
gives it more meaning, like I wrote in the review of patch 9/37.

Thanks,
Joao
