drm/i915: Add background commentary to "waitboosting"
Describe the intent of boosting the GPU frequency to maximum before
waiting on the GPU.
RPS waitboosting was introduced with commit b29c19b64528 ("drm/i915:
Boost RPS frequency for CPU stalls") but lacked a concise comment in the
code to explain itself.
