mtd: ubi: Add API calls to create/remove volumes
Currently we use a ioctl API to create/remove ubi volumes. This
means we always have to carry all function code for ubi volume
manipulation when the ioctl is compiled in.
This adds a function API to create/remove volumes so that the linker
can throw the unused code away later.
