Subject: [PATCH 2/2] platform/surface: aggregator_registry: Add support for Surface Pro 9

Add device nodes to enable support for battery and charger status, the
ACPI platform profile, as well as internal and type-cover HID devices
(including sensors, touchpad, keyboard, and other miscellaneous devices)
on the Surface Pro 9.

This does not include support for a tablet-mode switch yet, as that is
now handled via the POS subsystem (unlike the Surface Pro 8, where it is
handled via the KIP subsystem) and therefore needs further changes.

While we're at it, also add the missing comment for the Surface Pro 8.
