The pcf8563 interrupt line goes to GPIOX_5, so once that interrupt is described [1], its alarm wakes the board from s2idle but not from deep sleep. meson-vrtc is a register the SoC firmware reads when the application processors suspend, so it wakes the board from deep sleep only, and only with a BL301 that handles its alarm. List the states per RTC, so that alarmtimer programs the pcf8563 for s2idle and meson-vrtc for deep sleep.
