drm/amd/display: Fix HDMI framepack 3D test issue
[why]
Bandwidth validation failure on framepack tests.
Need to double pixel clock when 3D format is
framepack. Also for HDMI displays, we need to
keep the ITC flag to 1 by default.
[how]
Double the pixel clock when using framepack 3D format.
Set hdmi ITC bit to 1.
