add support for the fine3399 with the Linux 6.1

[Lemon1151]

Which feature would you like to have?

Hello, I would like to add support for the fine3399 with the Linux 6.1 kernel into the main Armbian source code. This is because the Linux 6.1 kernel and its earlier versions support the st77xx series of small screens, whereas starting from the Linux 6.6 kernel, subsequent versions no longer provide support for the st77xx series. How should I proceed to achieve this goal?
