resync mtd, ubi and ubifs subsystem with linux:

commit 455c6fdbd219161bd09b1165f11699d6d73de11c
Author: Linus Torvalds <torvalds at linux-foundation.org>
Date:   Sun Mar 30 20:40:15 2014 -0700

    Linux 3.14

Main reason for this sync is, we now have UBI fastmap support
in U-Boot.

Tested it on am33xx, imx6 and mpc83xx boards. MAKEALL for arm and powerpc
compiles clean.

Tested UBI fastmap on a board with 512 MiB nand flash. Attach time
from old U-Boot was 2 seconds, reduced with UBI fastmap to 0.2 seconds.

Please test this patchserie!

The patches 

  lib, rbtree: resync with Linux-3.14
  lib, list_sort: add list_sort from linux 3.14
  mtd, ubi, ubifs: resync with Linux-3.14

are not checkpatch clean, as they use code from Linux and
I do not want to change this.

Remarks:
- UBI Fastmap is now availiable in U-Boot
  activate it with CONFIG_MTD_UBI_FASTMAP

- replace UBI_LINUX in current UBI code from U-Boot with
  __UBOOT__ as this define is used in other places in U-Boot
  where code from other projects is used.

- move a lot of defines from include/ubi_uboot.h to
  include/linux/compat.h, as this is the correcter place for it.

- add usb device to linux device, so usb uses "struct device"
  from "linux/compat.h"

- onenand changes only compile tested.

- Following Code in drivers/mtd/nand/nand_base.c nand_do_write_ops()
  adapted for U-Boot:

  +#ifndef __UBOOT__
        /* Reject writes, which are not page aligned */
        if (NOTALIGNED(to) || NOTALIGNED(ops->len)) {
  +else
  +     /* Reject writes, which are not page aligned */
  +     if (NOTALIGNED(to)) {
  +endif

  as the original linux code leads in not working use of the env
  var "filesize". For example a "nand write 80000000 80000 ${filesize}"
  would not work with it ...

- add CONFIG_MTD_NAND_VERIFY_WRITE from U-Boot code
  (only compile tested)

- Documented the config defines in README

- kmalloc now uses memalign for allocating memory. This prevented
  crashes when tested ubi/ubifs on imx6 board.

- To produce this patch I did three steps:
  - copied the linux source files to U-Boot tree -> commit this
  - adapt license text in each file -> commit this
  - make the code again compile clean and working -> commit this

  Then squashed this three patches to this patch, to not break
  bisectability. To make further sync with linux easier, the
  above three patches can be found in:

  http://git.denx.de/?p=u-boot/u-boot-testing.git;a=shortlog;h=refs/heads/update-mtd%2Bubi-linux-v3.14

  This branch is only thought for further linux syncs! Please
  do not use this branch for testing this patchseries!

- Hope I get all U-Boot specific changes ... so please, test,
  test, test ...

- changes for v2:
  - add lib/linux_compat.c as Joerg Krause detected
