/* Delay a bit after enabling the LDC. I presume that a delay of a few
* frame times allows some unstable clocking to synchronize before we
* tart thrashing the framebuffer? But I am not sure why this is
* start thrashing the framebuffer? But I am not sure why this is
* necessary and, in fact, is certainly not necessary in most LCDC
* configurations. Perhaps this delay would not be necessary if timings
* were more precise?
