stdlib.h is the header for malloc since at least c89/c90.
Previously this would fail to build on OpenBSD and fallback to the wrong
header:

In file included from u-boot/tools/file2include.c:21:
u-boot/include/malloc.h:875:5: error: function-like macro
      'CONFIG_IS_ENABLED' is not defined

file2include is used to convert a binary file to a C include.
With the patch the SPDX header is written to the first line as
expected by scripts/checkpatch.pl.

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

For testing EFI disk management we need an in-memory image of
a disk.

The tool file2include converts a file to a C include. The file
is separated into strings of 8 bytes. Only the non-zero strings
are written to the include. The output format has been designed
to maintain readability.

 #define EFI_ST_DISK_IMG { 0x00010000, { \
  {0x000001b8, "\x94\x37\x69\xfc\x00\x00\x00\x00"}, /* .7i..... */ \
  {0x000001c0, "\x02\x00\x83\x02\x02\x00\x01\x00"}, /* ........ */ \
  {0x000001c8, "\x00\x00\x7f\x00\x00\x00\x00\x00"}, /* ........ */ \
  {0x000001f8, "\x00\x00\x00\x00\x00\x00\x55\xaa"}, /* ......U. */ \
 ...
  {0x00006000, "\x48\x65\x6c\x6c\x6f\x20\x77\x6f"}, /* Hello wo */ \
  {0x00006008, "\x72\x6c\x64\x21\x0a\x00\x00\x00"}, /* rld!.... */ \
  {0, NULL} } }

As the disk image needed for testing contains mostly zeroes a high
compression ratio can be attained.
