drm/amd/display: Use HDMI FreeSync range from common EDID parser

Browse source

HDMI FreeSync on amdgpu is detected using the AMD VSDB parser in the
DMUB firmware, now that the common DRM EDID parser can do the same, use
the common parser.

Extend get_amd_vsdb() to copy the relevant flags and data now being
extracted from the AMD VSDB. Additionally, parse_hdmi_amd_vsdb() and the
parse_edid_cea() firmware helpers now have no callers; remove them.
