of_pci_get_host_bridge_resources() allocates a list of resources for host
bridge windows. If we fail after allocating that list, free it before we
return error.

Previously we allocated the PCI resource list in
gen_pci_parse_request_of_pci_ranges(), but if we had an error, we freed it
on error in gen_pci_init().
Reorder gen_pci_init() so we can take care of error path cleanup in
gen_pci_parse_request_of_pci_ranges() instead.

The switch is the only statement in the resource_list_for_each_entry()
loop, so remove unnecessary cases and "continue" statements in the switch.
Inline rcar_pcie_release_of_pci_ranges(), which is only called once.
