power: smb1351-charger: Enable the charge termination during JEITA

If SoC (state of charge) based charging termination is used, when the
JEITA condition hits and battery voltage higher than the JEITA compensated
floating voltage, the switch mode charger would keep working even vbatt
is higher than its output. This puts the charger into reverse boost and
prevents the charger removal detection.

Fix this by changing to current based termination during JEITA. This turns
off the buck avoiding reverse boost. Restore to SoC based charging
termination when JEITA condition exits, and re-enable charging if SOC is
not FULL.

While at it, force SMB into pre-charge to allow it to draw less than 1000mA
to adhere to the JEITA spec.
