The MIPI DSI do not need check the validity of resolution, the max resolution should depend VOP. Hence, remove rk3288_mipi_dsi_mode_valid here.
Does vop actually enforce this, though? I see that mode_config.max_width is 4096, but there is no bounds checking in mode_fixup().
The connector is currently rejecting everything greater than 2047. So I think you're going to regress behavior here.
