[PATCH] rockchip: rk3308: Drop unused rk_board_init()

Jonas Karlman
2024-11-02T20:45:36Z

Nothing is calling the function rk_board_init() and the io-domain driver
can handle the functions intended purpose based on information from DT.

Cleanup by removing the unused rk_board_init() function and re-sort
included headers.
