power: qpnp-smbcharger: fix charger LED initialization

The default charger LED configuration is blink pattern '1'.
In case of software controlled charger LED configuration
the LED will start blinking unless userspace turns it off.

Initialize LED configuration as 'off' in case of software
controlled configuration.
