checkpatch: allow optional shorter config descriptions
This script is used by many other projects, and in some of them the
requirement of at least 4 line long description for all Kconfig items is
excessive. This patch adds a command line option to control the required
minimum length.
Tested running this script over a patch including a two line config
description. The script generated a warning when invoked as is, and did
not generate it when invoked with --min-conf-desc-length=2.
