device is very similar to samsung-gts210vewifi (SM-T813), just has additional LTE modem. Have to use gcc6 for kernel compilation, otherwise get 'Unhandled fault: alignment fault (0x96000061) at 0xffffff8001787f4c' errors on kernel startup, and device always reboots. [ci:skip-build]: already built successfully in CI
