Subject: [PATCH 9/9] intel_idle: Update copyright notice, known limitations and version

From: "Rafael J. Wysocki" <rafael.j.wysocki@...el.com>

Update the copyright notice in intel_idle.c to cover the recent
changes, drop the description of a "known limitation" that is not
a limitation any more and bump up the driver version number.

No functional impact.
