[Intel-xe] [PATCH 4/4] drm/xe: Stop tracking 4-tile support

[Matt Roper <matthew.d.roper@intel.com>]

The choice of Y-major tiling format (either the legacy "TileY" or the
newer "Tile4") is based on graphics IP version (12.50 and beyond have
Tile4, earlier platforms have TileY).  Only display was using the
has_4tile feature flag, but that handling is now self-contained within
the display code itself, so we no longer need to track this feature flag
in the main Xe driver.
