intel_idle: Update copyright notice, known limitations and version

Browse Source 
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.

/*
* Known limitations
*
* The driver currently initializes for_each_online_cpu() upon modprobe.
* It it unaware of subsequent processors hot-added to the system.
* This means that if you boot with maxcpus=n and later online
* processors above n, those processors will use C1 only.
*
* ACPI has a .suspend hack to turn off deep c-statees during suspend
* to avoid complications with the lapic timer workaround.
* Have not seen issues with suspend, but may need same workaround here.
