There's a bug on ACPI platforms where host events from the ECPD ACPI
device never make their way to the cros-ec-usbpd-charger driver. This
makes it so the only time the charger driver updates its state is when
user space accesses its sysfs attributes.

Now that these events have been unified into a single notifier chain on
both ACPI and non-ACPI platforms, update the charger driver to use this
new notifier.

I did not add any capacity prediction as that should probably be

some battery statistics and then the kernel driver could display the
capacity based on that.

an embedded ARM device that can use 6 AA batteries or a special rechargeable
Li-ion battery pack. The rechargeable battery pack presses a special key
switch in the battery compartment to indicate that it is present.

The EV3 is only capable of monitoring battery voltage and current. The
charging circuit is built into the rechargeable battery pack and there is
no way to communicate with is, so we can't provide any information about
charging status.

When not using the rechargeable battery pack, it is most common to use
alkaline batteries to power the device, but it is also common for people to
use rechargeable NiMH batteries. Since there is not a way to automatically
differentiate between these, the technology property is made writable.
