[PATCH] drm/i915/display: duplicate 128-byte Y-tiling feature check

[Jani Nikula <jani.nikula@intel.com>]

We should try to get rid of checks that depend on struct
drm_i915_private (or struct xe_device) in display
code. HAS_128_BYTE_Y_TILING() is one of them. In the interest of
simplicity, just duplicate the check as HAS_128B_Y_TILING() in display.
