[PATCH 13/38] drm/amd/display: build up VSIF infopacket

[Bhawanpreet Lakha]

From: Wayne Lin <Wayne.Lin at amd.com>

[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.
