[igt-dev] [PATCH i-g-t v2 02/16] lib/intel_device_info: Add a flag to indicate tiling 4 support

[Jeevan B <jeevan.b@intel.com>]

From: Mika Kahola <mika.kahola@intel.com>

Add tiling 4 support flag for DG2 platform. This is similar that
we have defined in kernel i915_pci.c intel_device_info() for DG2.
