[Intel-xe] [PATCH v2 0/6] i915: Move display identification/probing under display/

[Matt Roper]

Since i915's display code will soon be shared by two DRM drivers (i915
and Xe), it makes sense for the display code itself to be responsible
for recognizing the platform it's running on rather than relying on the
making the top-level DRM driver handle this.  This also becomes more
important for all platforms MTL and beyond where we're not really
supposed to identify platform behavior by PCI device ID anymore, but
rather by the hardware IP version reported by the device through the
GMD_ID register.

This series creates a more well-defined split between display and
non-display deviceinfo/runtimeinfo and then moves the definition of the
display-specific feature flags under the display/ code.  Finally, it
switches MTL (and all future platforms), to select the display feature
flags based on the hardware's GMD_ID identification.

v2:
 - Move DISPLAY_INFO() definition one patch earlier.  (Andrzej)
 - Rename display's runtime default structure to __runtime_defaults to
   make it more clear what the purpose is.  (Andrzej)
 - Simplify copy of runtime defaults to per-device runtime data.
   (Andrzej)
 - Fix uninitialized ptr use on error path during device probe. (lkp)
 - Add extra patch moving display-specific feature test macros to
   display/intel_display_device.h
