ACPI: battery: asynchronous init
The battery driver tends to take quite some time to initialize (100ms-300ms is quite typical). This patch initializes the batter driver asynchronously, so that other things in the kernel can initialize in parallel to this 300 msec. As part of this, the battery driver had to move to the back of the ACPI init order (hence the Makefile change). Without this move, the next ACPI driver would just block on the ACPI/devicee layer semaphores until the battery driver was done anyway, not gaining any boot time.
