drm/i915/bdw: GEN-specific logical ring init
Logical rings do not need most of the initialization their
legacy ringbuffer counterparts do: we just need the pipe
control object for the render ring, enable Execlists on the
hardware and a few workarounds.
v2: Squash with: "drm/i915: Extract pipe control fini & make
init outside accesible".
