There is a small memory leak in intel_modeset_readout_hw_state,
plug it.
intel_sanitize_crtc should set a null mode when disabling the crtc,
this updates crtc_state->enable too.
intel_sanitize_crtc also needs to update the vblank timestamps before
enabling vblank to make it work right.
Changes since v1:
- Moved after reworking primary plane and updating mode members.
- Force a modeset calculation by changing mode->type from what the
final mode will be.
Changes since v2:
- Do not fill out mode, this should only be done for supporting fastboot.
