Subject: drm/i915/gem: Merge GGTT vma flush into a single loop
Git-commit: 62d1c851466be84e725e1b7ca0662da5eea204e6
Patch-mainline: v5.6-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
We only need the one loop to find the dirty vma flush them and their
chipset.
