drm/i915: Convert intel_pipe_will_have_type() to using atomic state
Pass a crtc_state to it and find whether the pipe has an encoder of a given type by looking at the drm_atomic_state the crtc_state points to. Until recently i9xx_get_refclk() used to be called indirectly from vlv_force_pll_on() with a dummy crtc_state. That dummy crtc state is not converted to be part of a full drm atomic state, so add a WARN in case someone decides to call that again with a such dummy state. This was removed in commit 9cbe40c1 Author: Vijay Purushothaman <vijay.a.purushothaman@linux.intel.com> Date: Thu Mar 5 19:33:08 2015 +0530 drm/i915: Update prop, int co-eff and gain threshold for CHV v2: Warn if there is no connectors for a given crtc.
