drm/i915: Make execlist port count variable
As we emulate execlists on top of the GuC workqueue, it is not
restricted to just 2 ports and we can increase that number arbitrarily
to trade-off queue depth (i.e. scheduling latency) against pipeline
bubbles.
v2: rebase. better commit msg (Chris)
v3: rebase
