drm/amd/display: Clean up FreeSync capability detection

Browse source

Many duplicate codes can be extracted to common code, fill
amdgpu_dm_connector fields outside of the DP/eDP, HDMI branches,
pull the VSDB data once using get_amd_vsdb() and then derive the refresh
rate ranges.

When a monitor advertises support for FreeSync, the refresh rate from
the AMD VSDB is used, otherwise, falls back on the monitor_range, either
EDID refresh rate range field or DisplayID VRR data.
