Subject: drm/amd/display: build up VSIF infopacket
Git-commit: d832fc3b182045185e3dd92e20ac31c84be68da7
Patch-mainline: v5.5-rc1
References: bsc#1152489
[Why]
Didn't send VSIF infopacket when it's 4k mode defined in HDMI 1.4b.
For HDMI 1.4b, While displaying 4k modes, it should send VSP.
[How]
Call mod_build_hf_vsif_infopacket() function to build info frame
and send it.
