Rockboy: revert FS#11745 patch

William Shipley sent this patch via mailing list. Original Message:
  "There was a patch to rockboy in 2010 that fixed a problem where
  the bottom tile row would be rendered at the top.

  Here's the relevant issue from that time:
  http://www.rockbox.org/tracker/11745

  Note that Stummi openly admits it was a hack, not a true fix.

  Sometime in the 6 years since, the root cause was fixed. Currently,
  rockboy on the Clip+ and other 64px models shows the top of the gb
  screen along the bottom of the display.

  I confirmed that reversing this patch fixes the issue on my own
  Clip+"

I don't have any of the mentioned targets, so someone else has to test.
