Merge branch 'pci/controller/rzg3s-host'

- Use pci_generic_config_write(), not custom wrapper, since we don't need
  the writability provided by the wrapper (Claudiu Beznea)

- Drop lock around RZG3S_PCI_MSIRS and RZG3S_PCI_PINTRCVIS updates since
  they are RW1C registers (Claudiu Beznea)

- Fix a device node reference leak in rzg3s_pcie_host_parse_port() (Felix
  Gu)
