UPSTREAM: mtd: move NAND files into a raw/ subdirectory

NAND flavors, like serial and parallel, have a lot in common and would
benefit to share code. Let's move raw (parallel) NAND specific code in a
raw/ subdirectory, to ease the addition of a core file in nand/ and the
introduction of a spi/ subdirectory specific to SPI NANDs.

UPSTREAM: libfdt: move headers to <linux/libfdt.h> and <linux/libfdt_env.h>

Thomas reported U-Boot failed to build host tools if libfdt-devel
package is installed because tools include libfdt headers from
/usr/include/ instead of using internal ones.

This commit moves the header code:
include/libfdt.h -> include/linux/libfdt.h
include/libfdt_env.h -> include/linux/libfdt_env.h

and replaces include directives:
#include <libfdt.h> -> #include <linux/libfdt.h>
#include <libfdt_env.h> -> #include <linux/libfdt_env.h>

The current table look-up for the DTB file name turned out bothersome

There is a common pattern between the DT compatible string and the
corresponding file name; drop the vendor prefix "socionext," and
prefix it with "uniphier-" and suffix it with ".dtb".

ARM: uniphier: support USB boot mode for ProXstream2 / PH1-LD6b SoC

The USB boot code is too fat and complicated to be included in SPL
(at least for now). So, it was implemented as a separate project
(what we call USB-loader).

The expected boot sequence is as follows:

Boot ROM -> USB-loader -> SPL -> U-Boot proper

The USB-loader loads the SPL and U-Boot proper from a USB memory
onto the locked L2 cache. Then, SPL needs to copy the U-Boot proper
to DRAM, so this mode looks like a NOR boot from the view of SPL.
However, we want to distinguish between (genuine) NOR boot and USB
boot in some places.

ARM: uniphier: set DTB file name to fdt_file environment

When we want to boot Linux with a DTB file downloaded from a TFTP
server or somewhere, we need to know the file name to be downloaded.

Assume the U-Boot configuration is shared among some similar boards.
If they are similar enough, the difference only appears in device
trees. The build procedure would be like this:

- Board A: make foo_common_defconfig && make DEVICE_TREE=foo_board_a
- Board B: make foo_common_defconfig && make DEVICE_TREE=foo_board_b
- Board C: make foo_common_defconfig && make DEVICE_TREE=foo_board_c

In this case, the U-Boot image contains nothing about the DTB file name
it is running with. (CONFIG_DEFAULT_DEVICE_TREE is not helpful for this
purpose because it is painful to change it from "make menuconfig" for
each board.)

This commit allows to lookup the DTB file name based on the compatible
string and set it to "fdt_file" environment. Then "tftpboot $fdt_file"
will download the file we want.
