mtd: mtdpart: implement proper partition handling
Instead of collecting partitions in a flat list, create a hierarchy
within the mtd_info structure: use a partitions list to keep track of
the partitions of an MTD device (which might be itself a partition of
another MTD device), a pointer to the parent device (NULL when the MTD
device is the root one, not a partition).
By also saving directly in mtd_info the offset of the partition, we
can get rid of the mtd_part structure.
