This is adding the timer timer tests as standard kselftests to be run by
the wrapper script...

+int main(int argc, char *argv[])
+{
+	int device, subdevice, timeout;
+
+	if (argc < 4) {
+		perror("Usage: %s <device> <subdevice> <timeout>");
+		return EXIT_FAILURE;
+	}

...but this requires specific arguments to be run which the kselftest
runner won't supply.  I'd expect it to be a good default to enumerate
and test every possible device and generate a test for each.  However it
looks like this is really intended not as a standalone test but rather
as something run from within utimer-test, in that case it should be a
TEST_GEN_PROGS_EXTENDED.
