drm/i915/execlists: Skip forcewake for ELSP submission
Now that we can read the CSB from the HWSP, we may avoid having to perform mmio reads entirely and so forgo the rigmarole of the forcewake dance. v2: Include forcewake hint for GEM_TRACE readback of mmio. If we don't hold fw ourselves, the reads may return garbage.
