    Add ROHM BD71837 / BD71847 specific device tree bindings for
    controlling the PMIC shutdown/reset states and voltages for
    different HW states. The PMIC was designed to be used with NXP
    i.MX8 SoC and it supports SNVS low power state which seems to
    be typical for NXP i.MX SoCs. However, when SNVS is used we must
    not allow SW to control enabling/disabling those regulators which
    are crucial for system to boot as there is a HW limitation which
    causes SW controlled regulators to be kept shut down after SNVS
    reset.
    
    Allow setting the SNVS to be used as reset target state and allow
    marking those regulators which are critical for boot.
