Nirmoy Das 31c3c53ee3 drm/i915: Refactor confusing __intel_gt_reset()
__intel_gt_reset() is really for resetting engines though
the name might suggest something else. So add a helper function
to remove confusions with no functional changes.

v2: Move intel_gt_reset_all_engines() next to
    intel_gt_reset_engine() to make diff simple(John)
