drm/i915: fix device info for devices without display
Commit 00c6cbfd4e8a ("drm/i915: move pipe_mask and cpu_transcoder_mask
to runtime info") moved the pipe_mask member from struct
intel_device_info to intel_runtime_info, but overlooked some of our
platforms initializing device info .display = {}. This is significant,
as pipe_mask is the single point of truth for a device having a display
or not; the platforms in question left pipe_mask to whatever was set for
the platforms they "inherit" from in the complex macro scheme we have.
Add new NO_DISPLAY macro initializing .__runtime.pipe_mask = 0, which
will cause the device info .display sub-struct to be zeroed in
intel_device_info_runtime_init(). A better solution (or simply audit of
proper use of HAS_DISPLAY() checks) is required before moving forward
with [1].
Also clear all the display related members in runtime info if there's no
display. The latter is a bit tedious, but it's for completeness at this
time, to ensure similar functionality as before.
