libfdt: change fdt.h to a wrapper of scripts/dtc/libfdt/*

Fortunately, U-Boot did not modify fdt.h locally.

Change it to a wrapper of scripts/dtc/libfdt/fdt.h, which will be
periodically synced with the upstream DTC (or kernel).

Do not attempt to use the systemwide libfdt

U-Boot bundles a patched copy of libfdt, so it's wrong to attempt to
include it <like/this>. This breaks the build for me when I have dtc
fully installed in my host -- as happened earlier tonight with
Buildroot, for example.

There are several other occurrences throughout the code where '<libfdt'
matches. I'm not modifying these because I have no clue why the
<systemwide> include style is being used -- IMHO wrongly.

fdt: Move header files into lib/libfdt

These header files are actually part of libfdt. Move them there to make
it easier to build pylibfdt and easier to merge changes from upstream.

Update the license header to use SPDX at the same time.

fdt: Use SPDX format for licenses in the libfdt headers

These should follow the UBoot standard. Update them.

Move FDT_RAMDISK_OVERHEAD from fdt.h to libfdt_env.h

The define should not have been put in fdt.h originally, libfdt_env.h
is the proper place for target-specific customizations.

Added license header to dtc/libfdt/fdt.h and libfdt_env.h

This commit adds a license header to fdt.h and libfdt_env.h
because the license was omitted.

U-Boot note: the u-boot libfdt_env.h header portion was not applied to
the u-boot libfdt_env.h because that file was created by Gerald Van Baren
(with a license header). - gvb

powerpc: Fix bootm to boot up again with a Ramdisk

Commit 2a1a2cb6 didnt remove the dummy mem reservation in fdt_chosen,
and this stopped Linux from booting with a Ramdisk. This patch fixes
this, by deleting the useless dummy mem reservation.

When booting with a Ramdisk, a fix offset FDT_RAMDISK_OVERHEAD is now
added to of_size, so we dont need anymore a dummy mem reservation.

I measured the value of FDT_RAMDISK_OVERHEAD on a MPC8270 based
system (=0x44 bytes) and rounded it up to 0x80).

libfdt: Make fdt_check_header() public

Changed _fdt_check_header() to fdt_check_header() and made it part of
the interface - it is a useful routine.

Also did some asthetics cleanup to the include files (headers).

Minor cleanup.

libfdt: Import libfdt source (1 of 2)

This adds the applicable libfdt source files (unmodified) and a README
to explain where the source came from.
