A lot of files rely on include/driver.h including include/of.h (and
this including include/errno.h. include the files explicitly so we can
eventually get rid of including of.h from driver.h

Right now we do not support persistent names for mtd devices. The
base name can be passed to add_mtd_device, but this is always appended
with a dynamic number. With this patch add_mtd_device takes a device_id
argument which can be used to create a mtd device with an exact name.

This is a fresh UBI import from Linux v3.10

This is done mainly to get fastmap support.

This was tested with the i.MX nand driver, the MXS nand driver and
on CFI NOR flash.

This updates the NAND stuff to Linux-3.11-rc1. It is synchronized
as best as we can get:

- locks removed
- The splitting in different files we had to better support different
  features has been dropped. Instead this is now done mostly with the
  use of __maybe_unused

Some barebox adjustments are forward ported, like:

- Allow partial page writes
- Optionally allow to erase bad blocks
- check for all_ff before writing a page

While erasing bad blocks is a potentially dangerous operation
it is sometimes needed during development or when some foreign
code has touched the flash.

This patch adds a device parameter 'erasebad' to allow erasing
bad blocks. Since this is not wanted during production this is
behind a Kconfig option.

Do not write pages which only contain 0xff. UBI expects pages which
seem empty to be writable. This got lost with:

|    mtd core: call driver write function with complete buffer
|
|    mtd->write is supposed to loop around pages internally, no need
|    to do this in mtd_write. This fixes a huge write performance drop
|    with the m25p80 driver when it was converted to a mtd driver recently.
|    Since mtd->writesize is 1 for this driver mtd_write ended up doing
|    single byte writes on the flash.

Introduce mtd_all_ff as a global function since UBI currently has its own
implementation.

The Kernel has mtd_read, mtd_write, mtd_erase and mtd_block_markbad.
Add these functions to barebox aswell to make future mtd synchronizations
with the kernel easier.

Change NAND_WRITE into MTD_WRITE.
Change "page_shift" references in the core, which are purely
NAND, into mtd->writesize which is MTD generic.
Rename all "info" (struct mtd_info) into "mtd".

Also provide a parameter to add_mtd_device() so that legacy
nand devices still appear as nand<N>.
