[PATCH 02/15] mtd: nand: Add an helper returning the number of eraseblocks per target

[Miquel Raynal <miquel.raynal@xxxxxxxxxxx>]

From: Boris Brezillon <bbrezillon@xxxxxxxxxx>

Some drivers in the raw NAND framework seems to need this helper, so
let's just add it instead of open-coding the logic.
