drm/i915/tv: Fix modeset flickering introduced in 7f58aabc3
The tidy ups in 7f58aabc369014fda3a4a33604ba0a1b63b941ac ("drm/i915:
cleanup per-pipe reg usage") changed intel_crtc->plane to intel_crtc->pipe in
intel_tv_mode_set(). This caused the screen to quickly turn off before
returning whenever modesetting/mode probing took place on my 915GM EeePC
900 creating a flickering effect. This patch changes intel_crtc->pipe back
to intel_crtc->plane which solves the problem for me.
