Let the sdmmc adapters tell the sdmmc layer how much sectors they can
transfer with one command. Build on this and the recent minphys() changes
in the sdmmc layer to crank transfers at the maximum possible size instead
of a sad DEV_BSIZE.
Depending on your controller, this can speed up sdmmc I/O up to 2.5 times.
