Subject: [PATCH v6 08/10] power: supply: rt5033_battery: Adopt status property from charger
The rt5033-battery fuelgauge can't get a status by itself. The rt5033-charger
can, let's get this value.
To get the charger as a "supplier" from the devicetree, the "of_node" needs
to be initiated.
Additionally, in the probe function replace dev_err() with dev_err_probe(),
this will avoid printing an error for -EPROBE_DEFER when the battery driver
probes before the charger driver.
