Subject: [PATCH v2 3/6] arm64: dts: imx8mq-librem5: Add bq25895 as max17055's power supply

From: Sebastian Krzyszkowiak <sebastian.krzyszkowiak@...i.sm>

This allows the userspace to notice that there's not enough
current provided to charge the battery, and also fixes issues
with 0% SOC values being considered invalid.
