[PATCH] drm/i915/display: Do not report timeout on suspend

[Jonathan Cavitt <jonathan.cavitt@intel.com>]

In intel_dp_aux_wait_done, we call intel_de_wait_custom.  This call has
a 10ms timeout before reporting ETIMEDOUT.  However, if the display pm
runtime is suspended, then it would be expected for this call to time
out.  This may be the case, for example, during an engine reset.

Do not report ETIMEDOUT here when the pm runtime is suspended.
