Sharma, Swati2 Dec. 18, 2020, 10:33 a.m. UTC 
Instead of re-writing the avi_infoframe_compute func in intel_dp;
exporting hdmi_compute_avi_infoframe func so that it can be called
directly while encapsulating AVI infoframes in GMP dip.

This is required when HDMI 2.1 PCON (dp to hdmi) is used and we need
to send AVI infoframes to PCON in source control mode.
