[PATCH] mtd: document linux-specific partition parser DT binding

[Linus Walleij]

The Linux code in drivers/mtd/maps/physmap_of.c will optionally
look for this binding for hints on a partition type to look for
in the MTD. It was added in commit 9d5da3a9b849
"mtd: extend physmap_of to let the device tree specify the parition probe"
but no corresponding device tree binding was added. Fix this.
