staging: mt7621-mmc: set correct dma mask.
Since commit f8c55dc6e828 ("MIPS: use generic dma noncoherent ops for simple noncoherent platforms") changed MIPS dma handling, the mmc driver fails because it doesn't have a dma mask is set. So set the correct dma mask. Signed-off-by: NeilBrown <neil@brown.name> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
