drm/i915/gt: Flush before changing register state
Flush; invalidate; change registers; invalidate; flush.
Will this finally work on every device? Or will Baytrail complain again?

Fixes: ace44e13e577 ("drm/i915/gt: Clear CACHE_MODE prior to clearing residuals")
Testcase: igt/gem_render_tiled_blits # hsw-gt1
