Serge Semin 3869e9a3ba PCI: dwc: Convert dw_pcie_link_up() to use dw_pcie_readl_dbi() 
While the rest of the generic DWC PCIe code uses the dedicated IO-mem
accessors, the dw_pcie_link_up() method for some unobvious reason directly
calls readl() to get PortLogic.DEBUG1 register content. Since the way the
DBI bus is accessed can be platform-specific, use dw_pcie_readl_dbi()
instead so dw_pcie_link_up() is slightly more generic.
