It's not always the case that reboot mode value gets stored in PON register. For example, Sony Xperia M4 Aqua phone (MSM8939) uses a different set of mode values and stores them in IMEM. The series adds an optional DT property 'qcom,pon-reboot-not-used', and have PON driver skip reboot-mode setup if the property is present.
