samsung-starqltechn: add device SM-G9600

Device uses mainline kernel. What works:
- boots
- pstore log

* payload mock device tree:

Payload mock device tree is needed to mock device tree,
when we're overriding linux with u-boot in android boot image.
Stock bootloader needs this dtb appended to gzipped u-boot.

Bootscript is a simple hush shell script, dedicated to boot OS.
It may be customized to implement dual boot.
