mtd: rawnand: omap2: Use nand_controller_init()
Stop initializing omap_gpmc_controller fields are declaration time and
replace that by a call to nand_controller_init(). Since the same object
might be shared by several NAND chips and the NAND controller driver
expects a ->probe() per-chip, we need to keep track of the
omap_gpmc_controller state (whether it's already been initialized or
not).
