[Intel-gfx] [PATCH 1/3] drm/i915: move pipe, pch and vblank enable to encoders on DDI platforms

To allow better flexibility for encoder specific code, push
intel_enable_pipe(), lpt_pch_enable() and intel_crtc_vblank_on() down to
the encoders from hsw_crtc_enable().
There's slight duplication, but also more clarity with the reduced
conditional statements.
