Move S5P_INFORM5 write to aries_notifier_call.

Move write to S5P_INFORM5 (to show logo.jpg on reboot instead of
_charging.jpg when USB is connected, and possibly avoid LPM mode) from
arm_machine_restart to aries_notifier_call.  This better partitions this
device-specific operation, and makes it compatible with kexec hardboot.

This reverts commit 4bcead882b5d9a02985262609da5a17e15bbb8a1.
