The current code allows the TCON clock divider to have a range between 4 and 127 when feeding the DSI controller. The only display supported so far had a display clock rate that ended up using a divider of 4, but testing with other displays show that only 4 seems to be functional. This also aligns with what Allwinner is doing in their BSP, so let's just hardcode that we want a divider of 4 when using the DSI output.
