[WHY] Enabling NL SDR blending caused the 1D LUTs to be set/populated in two different functions. This caused flickering as the LUT was set differently by the two functions, one of which should only have been modifying the 1D LUT if 3D LUT was enabled. [HOW] Added check to only modify the 1D LUT in populate_mcm if 3D LUT was enabled. Added blend_tf function update for non-main planes if the 3D LUT path was taken. Reviewed-by:

[WHY] mod_hdcp_execute_and_set returns (*status == MOD_HDCP_STATUS_SUCCESS). When it return 0, it is guaranteed that status == MOD_HDCP_STATUS_SUCCESS will be evaluated as false. Since now we are using goto out already, all 3 if (status == MOD_HDCP_STATUS_SUCCESS) clauses are guaranteed to enter. Therefore we are removing the if statements due to redundancy. Reviewed-by:

[WHAT & HOW] According to register specifications, the CURSOR_DST_X_OFFSET is relative to the start of the data viewport, not RECOUT space. In this case we must transform the cursor coordinates passed to hubp401_cursor_set_position into viewport space to program this register. This fixes an underflow issue that occurs in scaled mode with low refresh rate. Reviewed-by:
