Document the RTL8365MB power rails as optional supplies. They are optional because the rails are often always-on; some designs break them out for granular hwmon monitoring and regulator control. They are scoped to realtek,rtl8365mb: different Realtek switch families use different power-rail naming schemes, so these rails do not apply to other families such as realtek,rtl8366rb (VDDA/VDD_CORE/VDDIO/...).
