Thanks to Maxime!

I have tried your repository on branch rpi4-kms.  The DRM VC4 is used!
But got some issues:
1. Some weird error message in dmesg.  Not sure it is related, or not
[    5.219321] [drm:vc5_hdmi_init_resources] *ERROR* Failed to get
HDMI state machine clock
https://gist.github.com/starnight/3f317dca121065a361cf08e91225e389

2. The screen flashes suddenly sometimes.

3. The higher resolutions, like 1920x1080 ... are lost after hot
re-plug HDMI cable (HDMI0)
