[PATCH 08/10] power: charger-manager: Not to start charging directly in cable nofitication.

This patch prevents direct charging control in cable notification.
It sets only input current limit according to cable type and yields charging
control to be done by cm_monitor() where charging management proceeds.
It may loose few ms to enable charging compared to before, even though it's
more important that charging is enabled always in safe context.
