drm/exynos: kill pipe field from drivers contexts
Since possible_crtcs are set by Exynos core helper pipe fields have no raison d'etre. The only place it was used, as a hack, is fimd_clear_channels, to avoid calling drm_crtc_handle_vblank, but DRM core has already other protection mechanism (vblank->enabled), so it could be safely removed.
