[dpdk-dev] [PATCH v3] devtools: export title syntax data for check-git-log

[Ferruh Yigit <ferruh.yigit@intel.com>]

From: Sean Morrissey <sean.morrissey@intel.com>

Moved title syntax to a separate file so that it improves code
readability and allows easy addition.

Also logic changed from checking for bad pattern to checking good
pattern which documents the expected syntax more clearly, and does not
have gaps in the checks.

v2:
* renamed data file to words-case.txt and added to MAINTAINERS file
* Updated script
* as of now vdpa as file prefix is giving false positive

v3:
* add check excluding file prefix to address vdpa false positive
* remove OCTEON_TX line from words-case.txt which was a mistake
