arm64: dts: rockchip: add DTs for Sakura Pi RK3308B
The Sakura Pi RK3308B is a SBC based on the Rockchip RK3308 SoC. Link: https://github.com/Sakura-Pi Link: https://docs.sakurapi.org/article/sakurapi-rk3308b/introduce The device contains the following hardware that is tested/working: - 4 or 8GB eMMC - SDMMC card slot - Realtek SDIO WiFi 5/BT - 256 or 512MB of RAM - USB 2.0 port - OTG port Signed-off-by: Hsun Lai <i@chainsx.cn> Link: https://lore.kernel.org/r/20250521131108.5710-4-i@chainsx.cn Signed-off-by: Heiko Stuebner <heiko@sntech.de>
