4883090bed cris: nand: use the mtd instance embedded in struct nand_chip 
struct nand_chip now embeds an mtd device. Patch all drivers to make use
of this mtd instance instead of using the instance embedded in their
private struct or dynamically allocated.

2d3743944a mtd: nand: docg4: simplify error case 
Other refactorings have left the 'fail' label much simpler, so it
shouldn't have to handle the failed allocation case.

This also fixes a -Wshadow warning.

the interrupt number in elm_probe:

drivers/mtd/nand/omap_elm.c:417:23: warning: format '%i' expects argument of type 'int', but argument 3 has type 'resource_size_t {aka long long unsigned int}' [-Wformat=]

665d2c2848 mtd: bcm47xxnflash: really unregister NAND on device removal 
The field bcma_nflash::mtd is never set to be non-zero anywhere, but we
test for it in the removal path. So the MTD is never unregistered.

Also, we should use nand_release(), not mtd_device_unregister().

Finally, we don't need to use the 'platdata' for stashing/retrieving our
*driver* data -- that's what *_{get,set}_drvdata() are for.

So, kill off bcm_nflash::mtd, and stash the struct bcm47xxnflash in
drvdata instead. Also move the forward declaration of mtd_info up a bit,
since struct bcma_sflash should be using it.

Caught while inspecting other changes being made to this driver. Compile
tested only.

NAND controller, otherwise the MTD attached to the NAND device is still
exposed by the MTD layer, and accesses to this device will likely crash
the system.

af3855dd19 mtd: brcmnand: Add support for the BCM6368 
The BCM6368 has a NAND interrupt register with combined status and enable
registers.

As the BCM6328, BCM6362 and BCM6368 all use v2.1 controllers, the first
variant that will work with this driver is the BCM63268 using a v4.0
controller.

Set up the device by disabling and acking all interrupts, then handle
the CTRL_READY interrupt.
