Bridges using DRM_BRIDGE_OP_HDMI are now expected to also provide a supported HDMI version. This is not yet enforced, but will become mandatory once the migration to the new caps-based HDMI connector initialization API is completed. Since inno_hdmi_phy_config.pixelclock does not exceed 165 MHz for any of the chip variants handled by the driver, advertise HDMI 1.2 as the supported version.
