[igt-dev] [PATCH i-g-t 2/5] RFC tests/i915/kms_frontbuffer_tracking: xe doesn't support tiling as of now

[Kunal Joshi <kunal1.joshi@intel.com>]

XE doesn't support tiling as of now, so set tiling to linear

v2: use is_xe_device() instead of static variable (Jouni)
    assert if xe device and unsupported tiling method specified
    in opt handler (Jouni)
v3: Fix condition in igt_assert
v4: Keep tiling check in igt_require (Bhanu)
