This brings the core NAND code up to date with the Linux kernel.

Since there were several drivers in Linux as of the last update that are
not in u-boot, I'm not bringing over new drivers that have been added
since in the absence of an interested party.

I did not update OneNAND since it was recently synced by Kyungmin Park,
and I'm not sure exactly what the common ancestor is.

onenand_print_device_info():
 - Now returns a string to be placed in mtd->name,
   rather than calling printf.
 - Remove verbose parameter as it becomes useless.

The block and page parameters of onenand_verify_page() are not used. This causes a compiler error when CONFIG_MTD_ONENAND_VERIFY_WRITE is enabled.
