drm/amd/display: Restore FreeSync VCP code check for HDMI/PCON sinks
[WHAT] Folding the MCCS FreeSync checks into the do_mccs block dropped the other half of the original condition: the check that clears freesync_capable for HDMI or PCON-in-whitelist sinks that expose no EDID FreeSync VCP code. That check does not depend on the MCCS caps and must run regardless of do_mccs. As a result, when do_mccs is false such a sink without a FreeSync VCP code is still reported as FreeSync-capable. [HOW] Restore the VCP code check outside the do_mccs block so it is evaluated whether or not MCCS caps were read.
