drm/i915: Make all GPU resets atomic

In preparation for the next few commits, make resetting the GPU atomic.
Currently, we have prepared gen6+ for atomic resetting of individual
engines, but now there is a requirement to perform the whole device
level reset (just the register poking) from inside an atomic context.
