Now with the watermarks fixes merged, Icelake is stable enough to have the alpha support protection flag removed. We have a few ICL machines in our CI and it is mostly green with failures in tests that will not impact future linux installations. Also there is no warnings, errors, flickering or any visual defects while doing ordinary tasks like browsing and editing documents in a dual monitor setup. As a reminder i915.alpha_support was created to protect future linux installation's iso images that might contain a kernel from the enabling time of the new platform. Without this protection most of linux installation was recommending nomodeset option during installation that was getting stick there after installation. Specifically, alpha support says nothing about the development state of the hardware, and everything about the state of the driver in a kernel release. This is semantically no different from the old preliminary_hw_support flag, but the old one was all too often interpreted as (preliminary hw) support instead of the intended (preliminary) hw support, and it was misleading for everyone. Hence the rename.
