pinctrl: Add pinctrl_pm_select_init_state helper function
If a platform requires an initial pinctrl state during probing, this
helper function provides the client with access to the same initial
state.
eg:
xxx_suspend_noirq
...
pinctrl_pm_select_sleep_state
xxx resume_noirq
pinctrl_pm_select_init_state
...
pinctrl_pm_select_default_state
