platform/surface: SAM: Add support for Surface Pro 12in

Browse Source 
Add a SAM client device node group and registry entry for the
Microsoft Surface Pro, 12-inch with Snapdragon.

This set enables the use of the following devices.
1: cover keyboard
2: cover touchpad
3: pen stash events.

The battery info and charger info devices have been
purposefully omitted as they are also reported by
other drivers and cause conflicts.
