Augment the only board file using this in the process and cut down on passed in platform data. Preserve the code setting the caps2 flags for CD and WP as active low or high since the slot GPIO code currently ignores the gpiolib polarity inversion semantice and uses the raw accessors to read the GPIO lines, but set the right polarity flags in the descriptor table for jz4740.
