drm/i915: Enable Resource Streamer state save/restore on MI_SET_CONTEXT
Also clarify comments on context size that the extra state for
Resource Streamer is included.
v2: Don't remove the extended save/restore enabled for older
platforms. (Ville)
Use new MI_SET_CONTEXT defines for HSW RS save/restore state
instead of extended save/restore. (Daniel)
