drm/bridge: Add bridge ops for source-side HDMI 2.0 scrambling

Browse source

Bridges advertising HDMI 2.0 must be able to enable and disable
source-side scrambling and the high TMDS clock ratio when the configured
mode exceeds 340 MHz.

Add .hdmi_scrambler_{enable|disable}() callbacks covering the
source-side programming only; sink-side SCDC negotiation remains the job
of the HDMI connector helpers.
