Merge branch 'pci/controller/stm32'

Browse Source 
- Update pinctrl documentation of initial states and use in runtime
  suspend/resume (Christian Bruel)

- Add pinctrl_pm_select_init_state() for use by stm32 driver, which needs
  it during resume (Christian Bruel)

- Add devicetree bindings and drivers for the STMicroelectronics STM32MP25
  in host and endpoint modes (Christian Bruel)

* pci/controller/stm32:
  MAINTAINERS: Add entry for ST STM32MP25 PCIe drivers
