drm/display: hdmi-state-helper: Set HDMI scrambling requirement
Set drm_connector_hdmi_state.scrambler_needed when the computed TMDS
character rate exceeds the HDMI 1.3 maximum TMDS character rate.
HDMI 2.0 requires scrambling above 340 MHz. Centralize that clock-based
requirement in the HDMI state helper so drivers do not need to open-code
the threshold check.
