[PATCH 06/10] drm/i915: Update legacy primary state outside the commit hook.

This should allow not running plane commit when the crtc is off.
While the atomic helpers update those, crtc->x/y is only updated
during modesets, and primary plane is updated after this function
returns.

Unfortunately non-atomic watermarks and fbc still depend on this
state inside i915, so it has to be kept in sync.
