[PATCH 0/1] rtc: rtctest: Support opal-rtc and rtc-generic

On ppc64le machines the opal-rtc, resp rtc-generic in guest is used. They only
support minimal set of functionality and fail this test in not-yet treated
way. This extends the checks and skips to the next test when feature is not
supported.

The rtc-generic and opal-rtc are failing to run this test as they do not
support all the features. Let's treat the error returns and skip to the
following test.

Theoretically the test_DATE should be also adjusted, but as it's enabled
on demand I think it makes sense to fail in such case.

Well, this needs to be fixed.

Yes, this chunk is actually not needed anymore (it was based on outdated copy we use in Autotest which had ENOTTY which is probably not needed nowadays). Let me send v2 without this.
