The DSI burst mode is more energy efficient than the DSI sync pulse mode,
make use of the burst mode since the chip supports it as well. Disable the
generation of EoT packet, the chip ignores it, so no point in emitting it.
Enable transmission of data in LP mode, otherwise register read via DSI
does not work with this chip.
