PCI: dwc: Move "dbi", "dbi2", and "addr_space" resource setup into common code
Most DWC drivers use the common register resource names "dbi", "dbi2", and
"addr_space", so let's move their setup into the DWC common code.
This means 'dbi_base' in particular is setup later, but it looks like no
drivers touch DBI registers before dw_pcie_host_init or dw_pcie_ep_init.
