Update U-Boot's version of scripts/get_maintainer.pl to sync it up with the
latest changes to the Linux kernel's version of the same script.

The last sync was with Linux kernel version v4.16. The commits to the kernel's
get_maintainer.pl since then (starting with the most recent) are:

	6343f6b71f83 get_maintainer: exclude MAINTAINERS file(s) from --git-fallback
	cdfe2d220476 get_maintainer: add test for file in VCS

The most significant change is the addition of the --self-test option
which allows to run a consistency check on all MAINTAINERS files.

Many MAINTAINERS files are in subdirectories.
We should enable searching these.

Update the script to version 0.26 (as of Linux v4.14-rc1)
Keep our "penguin_chief".
Keep our top_of_kernel_tree.

The negative forms of the command line parameters are described
when using --help.

New options are

 --git-blame-signatures => when used with --git-blame,
                           also include all commit signers
 --r => include reviewer(s) if any
 --letters => print all matching 'letter' types
              from all matching sections

File .get_maintainer.ignore can be used to specify
email addressees that shall be ignored.

from linux commit ce8155f7a3d5:

Perl 5.22 emits a deprecated message when "\C" is used in a regex.  Perl
5.24 will disallow it altogether.

Fix it by using [A-Z] instead of \C.

Looks like one spot got missed. Probably due to the backslash.

get_maintainer.pl always fails with following message:
./scripts/get_maintainer.pl: The current directory does not appear to be a linux kernel source tree.

This was caused by commit:

commit 548b310c68ac99a0330d8b56c797c09ff0742d1e

    Remove the CREDITS file

    This file is not maintained these days.

    We use MAINTAINERS for the maintainership of the supported boards.
    For dead boards, we have some clues in doc/README.scrapyard and
    also imperishable history in git-log.

Remove CREDITS from source tree detection to fix this.

Switch core maintainer to Tom Rini. Adapt directory layout for
git tree detection.
