MMC fixes for 3.3-rc4:
 * The most visible fix here is against a regression introduced in 3.3-rc1
   that ran cards in Ultra High Speed mode even when they failed to initialize
   in that mode, leading to lower-speed cards failing to mount.
 * A lockdep warning introduced in 3.3-rc1 is fixed.
 * Various other small driver fixes, most notably for a NULL dereference
   when using highmem with dw_mmc.
