mtd: Add DiskOnChip G3 support



Add support for DiskOnChip G3 chips. The support is quite
limited yet :
 - no flash writes/erases are implemented
 - ECC fixes are not implemented
 - powerdown is not implemented
 - IPL handling is not yet done

On the brighter side, the chip reading does work.

		This provides an MTD device driver for the M-Systems DiskOnChip
		G3 devices.

		The driver provides access to G3 DiskOnChip, distributed by
		M-Systems and now Sandisk. The support is very experimental,
		and doesn't give access to any write operations.
