PCI: dwc: all: Use platform_set_drvdata() to save private data

Browse Source 
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 structure 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.
