mmc: deprecate mmc bus topology
The classic MMC bus was defined as multi card bus system, which is reflected in the design in the MMC layer. When SD showed up, the bus topology was abandoned and a star topology (one card per host) was mandated. MMC version 4 has followed this, officially deprecating the bus topology. As we do not have any known users of the bus topology we can remove support for it. This will simplify the code and rectify some incorrect assumptions in the newer additions.
