On the am335x-icev2 board [1], AM3359 PMIC_PWR_EN (ZCZ ball C6) is
connected to PWRHOLD (pin 1) on the TPS65910A3 PMIC. The addition of
system-power-controller to the rtc node will enable the capability of
the RTC driver to poweroff the board.
Based on 15c7be47fb7c ("ARM: dts: am335x: Add rtc node as
system-power-controller") by Keerthy in ti-linux-5.4.y branch [2].
