Use functions provided by drivers/pci/ecam.h for mapping the config space in drivers/pci/host/pci-host-common.c, and update its users to use 'struct pci_config_window' and 'struct pci_ecam_ops'. The changes are mostly to use 'struct pci_config_window' in place of 'struct gen_pci'. Some of the fields of gen_pci were only used temporarily and can be eliminated by using local variables or function arguments, these are not carried over to struct pci_config_window. pci-thunder-ecam.c and pci-thunder-pem.c are the only users of the pci_host_common_probe function and the gen_pci structure; these have been updated to use the new API as well. The patch does not introduce any functional changes other than a very minor one: with the new code, on 64-bit platforms, we do just a single ioremap for the whole config space.
