mtk_mipi_tx is the phy of mtk_dsi.

So, mtk_mipi_tx init should be ahead of mtk_dsi. Or mtk_dsi will

horizontal_backporch_byte should be hbp * bpp - hbp extra bytes.

If panel has too small hfp or hbp, horizontal_frontporch_byte or
horizontal_backporch_byte may become very small value or negative

than minimum value and keep total of them unchanged.
