sommerfeld b8de140e4e Prototype ACPI Control Method Battery driver. 
ACPI defines two different battery device interfaces: "Control Method"
batteries, in which AML methods are defined in order to get battery
status and set battery alarm thresholds, and a "Smart Battery" device,
which is an SMbus device accessed through the ACPI Embedded Controller
device; this driver knows how to attach to the former sort of device.

As a total kludge, since we haven't wired things up to sysmon/envsys
yet, we report battery status through a once-per-minute kernel printf,
so don't use this driver yet if you want your disk to spin down.

Motivated by and tested on Sony PCG-R505TL laptop, which has
nonfunctional APM.
