linux/compat.h: rename from linux/mtd/compat.h

This lets us use it in more places than just mtd code.

onenand: Replace ONENAND_IS_MLC() with ONENAND_HAS_4KB()

This replacement causes 4KB page size devices to work properly with u-boot.

The old ONENAND_IS_MLC() behavior has been preserved by explicit
setting of ONENAND_HAS_4KB_PAGE for those devices.

This change makes the onenand_base.c file more resembling the respective
kernel sources.

onenand:samsung Target dependent OneNAND chip probe function

Separate callback for probing OneNAND memory chip.
If no special function is defined, default implementation will be used.

This approach gives more flexibility for OneNAND device probing.

OneNAND: Additional sync with 2.6.27

- Add subpage write support
- Add onenand_oob_64/32 ecclayout

This has been missing and without it UBI has some incompatibilies issues
with the current (>= 2.6.27) Linux kernel version. vid_hdr_offset is
placed differently (2048 instead of 512) without this fix.

NAND: sync with 2.6.27

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.
