Subject: drm/amd/display: Avoid sending abnormal VSIF
Git-commit: acf83f86b2e1dd39fdc4e5e7072aaf21d0563558
Patch-mainline: v5.5-rc1
References: bsc#1152472

[Why]
While setting hdmi_vic, hv_frame.vic is not initialized and might
assign a wrong value to hdmi_vic. Cause to send out VSIF with
abnormal value.

[How]
Initialize hv_frame and avi_frame
