drm/radeon: properly filter DP1.2 4k modes on non-DP1.2 hw
commit 410cce2a6b82299b46ff316c6384e789ce275ecb upstream.
The check was already in place in the dp mode_valid check, but
radeon_dp_get_dp_link_clock() never returned the high clock
mode_valid was checking for because that function clipped the
clock based on the hw capabilities. Add an explicit check
in the mode_valid function.
