[PATCH v2 6/6] selftests: move watchdog tests from Documentation/watchdog

From: Shuah Khan
Date: Tue Sep 13 2016 - 16:19:31 EST


Remove watchdog-test from Makefile to move the test to selftests.

Add Makefile and .gitignore to for watchdog-test. watchdog-test will
not be run as part of selftests suite and will not be included in
install targets. It can be built separately for now.
