block: move struct partition out of genhd.h
struct partition is the on-disk format of a MSDOS partition table entry. Move it out of genhd.h into a new msdos_partition.h header and give it a msdos_ prefix to avoid confusion. Also move the magic number from block/partitions/msdos.h to the new header so that it can be used by the SCSI drivers looking at the DOS partition tables.
