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.
