There is an issue with a display showing artifacts after leaving the display
blank for some time. If sel6_8 line stays high during the power-off of the
display, the display gets side-powered by the sel6_8 line. And the power
sequence during the next power up does not reset the display in a good state.

So switch the sel6_8 gpio to low, when the VDD-LCD is powered of, and enable it
to the correct state, just before the VDD-LCD is powered on again.
