The TC358767/TC358867/TC9595 are capable of DSI burst mode, which
is more energy efficient than the non-burst modes. Make use of it.
The TC358767/TC358867/TC9595 are capable of DSI non-continuous clock,
since it sources the internal PLL clock from external clock source.
The DSI non-continuous clock further reduces power utilization.
The TC358767/TC358867/TC9595 may use DSI LPM for command transmissions,
make sure this is configured correctly in the DSI mode flags.
