PCI: dwc: Allow overriding bridge pci_ops

Browse Source 
In preparation to allow drivers to set their own root and child pci_ops
instead of using the DWC specific config space ops, we need to make
the pci_host_bridge pointer available and move setting the bridge->ops
and bridge->child_ops pointer to before the .host_init() hook.
