The blocked off doorway is a remnant from the expanded original Japanese edition of the game. In Japan the "e-reader" system may be used to earn extra content at this location by scanning cards with special "dot codes." In America the "e-reader" system is available, and you can scan cards, but pretty much all you can do with it is get information on Pokemon and items. A function that is only really helpful when you're looking for the location of one particular pokemon. I suppose they figured it was easier to program in a tree rather that program out a door.
