video gfx: fix menu ordering

Move video graphics driver configs to fix menus:

Fix FB_PMAGB_B to depend on FB so that the FB menus remain
  listed in order and indented correctly.
Fix FB_IBM_GXT4500 to depend on FB so that the FB menus remain
  listed in order and indented correctly.
The OMAP FB drivers still muck up the FB menu a bit, so I put
  OMAP drivers at the end of the FB menu.
