arm64: dts: qcom: gaokun3: Add Embedded Controller node

Browse Source 
The Embedded Controller in the Huawei Matebook E Go is accessible on &i2c15
and provides battery and adapter status, port orientation status, as well
as HPD event notifications for two USB Type-C port, etc.

Add the EC to the device tree and describe the relationship among
the type-c connectors, role switches, orientation switches and the QMP
combo PHY.
