arm64: dts: ti: k3-am68-sk-base-board: Add HDMI support
AM68-SK has an HDMI port. The bridge used is TI-TFP410. Add support to enable the connection: DSS => TI TFP410 DPI-to-DVI Bridge => HDMI connector Signed-off-by: Jayesh Choudhary <j-choudhary@ti.com> Reviewed-by: Aradhya Bhatia <a-bhatia1@ti.com> Link: https://lore.kernel.org/r/20230803081800.368582-3-j-choudhary@ti.com Signed-off-by: Nishanth Menon <nm@ti.com>
