PCI: designware: Simplify pcie_host_ops.readl_rc() and .writel_rc() interfaces
The struct pcie_host_ops.readl_rc() and .writel_rc() function pointers allow a driver to override the default DesignWare register accessors. Make the signature of the override functions the same as the default accessors. This makes the default dw_pcie_readl_rc() and the corresponding override more structurally similar: both will compute the final register address with "pp->dbi_base + reg". Previously dw_pcie_readl_rc() computed the address and passed it to the override. No functional change intended. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
