This define allows to overwrite DMA_PIO_WORDS with an architecture
specific value. Since this is unused and not clean anyway remove
it.

MXS specific devices have some common infrastructure in the kernel
known as STMP devices. We have the same in barebox, but with a
mxs_ prefix instead of a stmp_ prefix. As some STMP devices are
also found on i.MX6 move the common infrastructure out of MXS
specific files and use the stmp_ prefix.
This is done in preparation for i.MX6 NAND support.

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

In the upcoming multi image build process we will cat images together.
To find the concatenated image we need to reliably find the end of the
current binary. This adds a dummy section at the end of a pbl binary.
Its only purpose is to mark the end of the image. The multi image
patches will add something to this section so that it doesn't get
discarded by the linker.

According to ePAPR 1.1 spec, device tree nodes status can be either
"okay", "disabled", "fail", or "fail-sss". Barebox already has a function
to check for "disabled" nodes, while Linux checks for "okay" or "ok".
To synchronize Barebox and Linux OF APIs, rename of_node_disabled to
of_device_is_available and check for "okay" instead of "disabled" as it
also makes "fail"ed devices unavailable.

Barebox of_find_node_by_path requires a node to be passed as start node
to start searching. Linux OF API does not pass this node and no current
user of it in barebox is passing anything else than the root node.
Therefore, we rename current function to of_find_node_by_path_from and
introduce a Linux OF API compatible of_find_node_by_path that always
passes the current root_node. Also, all current users of that function
are updated to reflect the API change.
