develop-5.10 内核在RK3399上 开源驱动 使用wayland模式 屏幕闪烁。

[IamHuskar]

由于4.4内核版本较低，想在rk3399上用develop-5.10内核 用开源驱动+wayland 提高性能。但是发现有闪烁。但是5.4的主线内核没有这个问题。能否修复一下这个屏幕闪烁的问题呢

更新一下 测试结果。直接用主线的 5.10.110的drm 也可以正常启动

用develop-5.10的drm 内部会报错。 采用的内核 commit id : a4423c56f430bfc7c75dbb68d4a9a1a0ef62b371 采用的rootfs : ubuntu22.04 base + palsma-desktop +wayland
