drm/i915/display: Add MTL subplatforms definition

Browse Source 
Separate MTL-U platform PCI ids in one define macro.

Add the MTL U/ARL U as subplatform member in MTL platform description
structure to use display.platform.<platform> from intel_display
structure instead of IS_<PLATFORM>() in display code path.

v2:
- Club ARL-u in MTL and identify ARL-u as MTL-u subplatform(Jani)
