lint/checkpatch.pl: Pull in coreboot fixes

This pulls in two fixes that were added to coreboot's checkpatch.pl
    script:

- commit 82ef8ada (src/commonlib/lz4_wrapper: Correct inline asm for
    unaligned 64-bit copy):
    modify checkpatch.pl to ignore spaces before opening brackets when
    used in inline assembly.

- commit ebef00fa (lint/checkpatch.pl: escape { in perl regex to fix
    warnings):
    Unescaped left brace in regex is deprecated, passed through in regex;
