Tested this on SM8350 which actually has DSI 2.5, and it is also
corrupted with this series so something else on this series might be
broken.

Never mind, this was a bad conflict-resolve. Jessica's original
BURST_MODE patch was RMW'ing MDP_CTRL2, but the upstreamed patch was
only writing, and the way I conflict-resolved that caused the write of
BURST_MODE to overwrite the RMW DATABUS_WIDEN.

If both are moved to dsi_ctrl_config(), we could do a read, add both
flags in conditionally, and write.


So just to confirm, there is no issue on your 8350 setup with widebus enabled right?
