mtd: Add flash_node in struct mtd_info
Currently, add_mtd_partitions_of() can be used only if dev field of
mtd_info struct is populated. It's the case, for example, for a spi nor
flash, which has a DT compatible "jedec,spi-nor" and an associated
device. mtd->dev is populated in spi_nor_scan().
But in case of a raw nand node, mtd_info's dev field can't be populated
as flash node has no compatible, so no associated device.
add_mtd_partitions_of() can't be used to parse "partitions" subnode.
To remove this constraint, add an ofnode field in mtd_info struct
which reference the DT flash node. This new field is populated by
nand_scan_tail(). This new field will be used by add_mtd_partitions_of()
to parse the flash node for "partitions" defined in DT.
