power: supply: bq25890: Enable charging on boards where we skip reset

On boards where the "linux,skip-reset" boolean property is set we don't
reset the charger; and on some boards where the fw takes care of
initalizition F_CHG_CFG is set to 0 before handing control over to the OS.

Explicitly set F_CHG_CFG to 1 on boards where we don't reset the charger,
so that charging is always enabled on these boards, like it is always
enabled on boards where we do reset the charger.
