[PATCH v3 14/16] PCI: dwc: spear13xx: Use cached PCIe capability offset

[Hans Zhang]

Inside .init we must call dw_pcie_get_pcie_cap() to obtain the offset,
because the core has not yet cached it. The hardware is already enabled
by the driver's own initialization before this point.

In pcie-spear13xx, the call chain is:

  static const struct dw_pcie_host_ops spear13xx_pcie_host_ops = {
    .init = spear13xx_pcie_host_init,
  };
  spear13xx_pcie_host_init()
    -> dw_pcie_find_capability()
