drm/amd/display: Send H14b-VSIF specified in HDMI

[Why]
Current function excludes the logic to generate H14b-VSIF. Now it
constructs HF-VSIF only and causes HDMI compliace test fail.

[How]
According to HDMI spec, source devices shall utilize the H14b-VSIF
whenever the signaling capabilities of the H14b-VSIF allow this.

Here keep the logic for HF-VSIF and add H14b-VSIF construction part.
