[RESEND PATCH 0/2] Add pinctrl_pm_select_init_state helper function

We have the helper functions pinctrl_pm_select_default_state and
pinctrl_pm_select_sleep_state.
This patch adds the missing pinctrl_pm_select_init_state function.

The STM32MP2 needs to set the pinctrl to an initial state during
pm_resume, just like in probe. To achieve this, the function
pinctrl_pm_select_init_state is added.

This allows a driver to balance pinctrl_pm_select_sleep_state()
with pinctrl_pm_select_default_state() and
pinctrl_pm_select_init_state() in pm_runtime_suspend and pm_runtime_resume.

Christian Bruel (2):
  pinctrl: Add pinctrl_pm_select_init_state helper function
  PCI: stm32: use pinctrl_pm_select_init_state() in
    stm32_pcie_resume_noirq()
