Subject: drm/i915/fbc: Rewrite the FBC tiling check a bit
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Git-commit: faca22fd5061c80ac9f5fd36dbcb174336cfbd33

References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225
Write the tiling check in a nicer form. No functional
changes due to Y-tile scanout being a gen9+ feature.
