[PATCH] mtd/powernv_flash: Enable partition support

[tpearson@xxxxxxxxxxxxxxxxxxxxx (Timothy Pearson)]

On certain systems, such as the Talos II, skiboot emits a partition
table for the main PNOR MTD device in the generated device tree.

Allow this partition table to be parsed and the partitions to be
exposed via MTD device partition nodes.
