PCI: intel-gw: Remove intel_pcie_cpu_addr() 

Remove intel_pcie_cpu_addr(), the .cpu_addr_fixup() method, because the dwc
core driver already handles address translation based on the devicetree
description.

[bhelgaas: this does require a minor dts change, but maintainer
Lei Chuan Hua <lchuanhua@maxlinear.com> confirms that the driver is only
used internally to Maxlinear and internal users will update dts:
