qpnp-rtc.c : Generate the node wakealarm for RTC 



If we execute function device_init_wakeup() after rtc_device_register()
It do not generate the wakealarm node at /sys/class/rtc/rtc0/, which is
used to set up wakealarm time.Because wakealarm node generates in function
rtc_device_register() and need device_init_wakeup() set the related flag 1,
the device_init_wakeup() must move before rtc_device_register().
