The 'debug' and 'printf' functions were previously added to the list of
logFunctions in commit 0cab42110dbf ("checkpatch.pl: Add 'debug' to
the list of logFunctions") and commit 397bfd4642c1 ("checkpatch.pl:
Add 'printf' to logFunctions") but these additions were lost when newer
versions of checkpatch were pulled in from the upstream Linux
kernel version.

This restores them so that you don't end up in a situation where
checkpatch will give a warning for "quoted string split across lines"
which you cannot fix without getting a warning for "line over 80
characters" instead.

Update from upstream.

Just minor changes like checking that the author has also done a sign-off.

Update scripts/checkpatch.pl from upstream.

One of the many corrections is not creating an error for cover-letters.

While there are valid reasons to use __packed, often the answer is that
you should be doing something else here instead.

Checkpatch produces the following warning:

Unescaped left brace in regex is deprecated here
(and will be fatal in Perl 5.30), passed through in regex;
marked by <-- HERE in m/^(\+.*(?:do|\))){ <-- HERE /
at scripts/checkpatch.pl line 3348.

The curent checkpatch of the Linux kernel corrects this
bug and many others.

It provides improved colored output.

So replace checkpatch by the current Linux version.

Add an empty file scripts/const_structs.checkpatch.
We can later fill it according to our needs.

checkpatch: fix left brace warning

Using checkpatch.pl with Perl 5.22.0 generates the following warning:

Unescaped left brace in regex is deprecated, passed through in regex;

This patch fixes the warnings by escaping occurrences of the left brace
inside the regular expression.

Adapt it for U-Boot.

checkpatch: remove unnecessary + after {8,8}

There's a useless "+" use that needs to be removed as perl 5.20 emits a
"Useless use of greediness modifier '+'" message each time it's hit.
