mtd: add support for parsing partitions defined in OF
Add support for parsing partitions defined in device-trees via the
`partitions` node with `fixed-partitions` compatible.
The `mtdparts`/`mtdids` mechanism takes precedence. If some partitions
are defined for a MTD device via this mechanism, the code won't register
partitions for that MTD device from OF, even if they are defined.
