mmc: remove multiwrite capability
Relax requirements on host controllers and only require that they do not report a transfer count than is larger than the actual one (i.e. a lower value is okay). This is how many other parts of the kernel behaves so upper layers should already be prepared to handle that scenario. This gives us a performance boost on MMC cards.
