Add initial support for the Samsung Galaxy S20 Series (hubble) phones.
They were launched in 2020, and are based on the Exynos 990 SoC.
The devices have multiple RAM configurations,
starting from 8GB going all the way up to 16GB for the S20 Ultra devices.

This device tree adds support for the following:

- SimpleFB
- 8GB RAM (Any more will be mapped in device trees)
- Buttons

There is only one user - your x1s - so we do not need common file,
unless you post immediately more users.

Best regards,
