After this bit is set transcoder hardware will automatically send the frame data to the panel in case of TE NO_GATE mode, where it sends after it receives the TE event in case of TE_GATE mode. Once the frame data is sent to the panel, we see the frame counter updating. v2: Use intel_de_read/write v3: remove the usage of private_flags v4: Use icl_dsi in func names if non static, fix code formatting issues.
