Some of the flags that were used are still useful when transitioning
to atomic, so keep those around for now. This removes some of the
complications of crtc->primary_enabled, making it easier to remove.

The crtc_enable hooks set intel_crtc->active, so the call to
intel_crtc_enable_planes() doesn't actually do anything because of the
new check in the hunk above.

This makes disabling planes more explicit.
Signed-off-by: Maarten Lankhorst <maarten.lankhorst@linux.intel.com>

Changes since v1:
- Create a intel_crtc_reset function for i915_debugfs.c instead of calling .crtc members directly.
- Remove the checks for intel_crtc->active, they're wrong. (thanks anderco)

Style recommendation in drm/i915 land is to put the per-patch changelog
before the cutoff. I know that often it contains just noise, but often the
commit message doesn't get updated with the new reasonings and these
breadcrumbs tend to be really valuable when trying to understand why a
patch was done in the future.
Thanks, Daniel

Ignore this patch for now, the transitional helpers don't call crtc check so it's useless to do until all transitional plane helpers are converted.
The other patches should still apply.
