Major numbers which are greater than 159 are already reserved for
the MI purpose, so we can already allocate/change the numbers without
changing the dev_t size.

On the other hand, It'd be nice to unify DISKUNIT(), DISKPART(),
DISKMINOR() and MAXPARTITIONS macros across the ports (without
changing the maximum number of partitions of on-disk disklabel
format).  64bit dev_t helps this.
