ExtremeXT/android_device_samsung_s5e9925-common ? reverse-engineered prompt

Build out the Android device support files for the Samsung s5e9925 common tree so it can be used with a Lineage based build.

I want the device config, vendor blob setup, overlays, sepolicy, shims, and build files to all work together cleanly so the device can compile and boot as far as possible. Please check the existing files, fill in anything missing, fix obvious build issues, and make sure the proprietary file handling and setup scripts are correct. If you need current Lineage or Android build info, look it up online and use the latest compatible approach.

Keep it focused on getting a solid, working device tree rather than adding extra features.
