From: Mauro Carvalho Chehab <mchehab@kernel.org>

Add a way to specify a set of default values to be used when numeric
wildcards like "%d" are present at the igt subtest.

+    It is also possible to define a list of values that will actually be
+    used by the test and no string replacement is needed.
