power: supply: bq25890: Add a bq25890_rw_init_data() helper

Browse source

On most x86/ACPI devices there is no devicetree to supply the necessary
init-data. Instead the firmware already fully initializes the bq25890
charger at boot.

Factor out the current code to write all the init_data from devicetree
into a new bq25890_rw_init_data() helper which can both write the data
to the charger (the current behavior) as well as read it back from
the charger into the init_data struct.

This is a preparation patch for adding support for x86/ACPI device's
where the init_data must be read back from the bq25890 charger.
