Generic board support is now enabled for Exynos 4, and if any
init function returns an error then the init process is stopped.

This makes a boot issue on the Trats and Trats2 devices. If the device
is supplied by USB cable or an external power supply then it can't boot
because function exynos_power_init returns an error. Now this function
returns 0 if battery is not connected.
