Subject: [PATCH 227/389] power: supply: axp20x-battery: Enable poweron by RTC
alarm
For the Pinephone to be able to poweron on RTC alarm, some bits in
PMIC need to be enabled. This will cause PMIC to be wakeable by
SoC pulling the interrupt line low.
This may need some coordination from a bootloader.
