mtd: nand: embed an mtd_info structure into nand_chip
Currently all NAND controller drivers are providing both the mtd_info and nand_chip struct and then let the NAND subsystem to initialize a few things before registering the mtd instance to the MTD layer. Embed an mtd_info field into nand_chip to add some consistency to all NAND controller drivers. This change will also help factorizing boilerplate code copied in all NAND drivers.
