PCI: host-generic: Eliminate pci_host_common_probe wrappers

Browse Source 
Most ECAM host drivers are just different pci_ecam_ops which can be DT
match table data. That's already the case in some cases, but let's
do that for all the ECAM drivers. Then we can use
of_device_get_match_data() in pci_host_common_probe() and eliminate the
probe wrapper functions and use pci_host_common_probe() directly for
probe.
