drm/i915/g33: Improve reset reliability

We improved the reset reliablity on gen4 with
stopping all engines before commencing reset, in
commit 2c80353f3cd0 ("drm/i915/g4x: Improve gpu reset reliability")

Evidence indicates that this same trick works with g33.

v2: proper gen naming, comment readability (Chris)
