lvgl/drivers: change rotation
Driver is able to rotate screen by changing
how addresses are change when data is
transmitted.
For 90 and 270 degree rotation screen appeared
to rotate clock wise. Problem pops up when
touch screen is present and in those rotations
touch screen orientation which does not changed
did not correspond to display orientation.
