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.
