matisse-common: fixed offline charging

* Wrong value of user_debug in cmdline prevented to try to boot in offline charging mode
* For charger, tell that we don't have a LED and to disable init blank (with this flag, charging mode showed animation, but didn't allow to show it another time when pressing power button to turn on the screen)
* Set a brightness value for charger. In this way, when power button is pressed, device turns on and shows battery icon correctly.
