board: 8064: Make HDMI as primary by default for MPQ

For MPQ CDP and HRD boards, HDMI needs to be the primary display
by default without having to specify it using boot parameters.
This change adds this feature with the added flexibility to
specify any other panel as primary using fastboot parameters.
