[PATCH] platform/surface: aggregator_registry: omit battery & AC nodes on Surface Laptop 7

[Oliver White]

Surface Laptop 7 exposes battery and AC status via Qualcomm PMIC GLINK
qcom_battmgr. Registering the standard SSAM battery and AC client
devices on this platform causes duplicate power-supply devices to
appear.

Drop the SSAM battery and AC nodes from the Surface Laptop 7 registry
group so that only the qcom_battmgr power supplies are instantiated.

Thank you for your contribution, it has been applied to my local
review-ilpo-fixes branch. Note it will show up in the public
platform-drivers-x86/review-ilpo-fixes branch only once I've pushed my
local branch there, which might take a while.
