Revert "drm/i915/icl: WaEnableFloatBlendOptimization"
The register for 0xe420 is unable to hold any value, including this bit. The documentation is also mixed between having a register bit for toggle and having a state command setup for it. Apparently the register toggle is deprecated. Remove the register toggle as evidence shows it's futile. The thing remaining is an apology and humble request for Mesa folks to resurrect their state setup for this as they were on right track from start. This reverts commit 0bf059f3532bb39c52d917142206a8554fc2f1c5.
