Some platforms need to set the pinctrl to an initial state during
pm_resume, just like during probe. To achieve this, the missing function
pinctrl_pm_select_init_state() is added to the list of already existing
pinctrl PM helper functions.
This allows a driver to use the pinctrl init and default states in the
pm_runtime platform resume handlers, just as in probe.
Additionally the missing documentation describing these pinctrl standard
states used during probe has been added.
This fixes a build issue for the STM32MP25 PCIe staged in the pcie tree,
id 5a972a01e24b
Changes in v1:
- Add missing information about PM helper functions.
