This goes back to pre-atomic, where due to intermediate dpms states
connectors and encoder states might indeed not have matched.
With atomic that's all smashed together (and hopefully no bios ever
enables a vga output in dpms standby/suspedn state or we're toast).

drm/i915: Remove connectors_active from sanitization, v2.
sanitize_encoders was changed to disable the encoder in all cases,
which made the comment obsolete.
Remove the misleading comment.
