Subject: drm/cirrus: Use offset-adjusted shadow-plane mappings
Git-commit: 12f84ab2ff568768699f73b0b32feebc25d38406
Patch-mainline: v5.15-rc1
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

For framebuffers with non-zero offset fields, shadow-plane helpers
provide a pointer to the first byte of the contained data. Use it in
cirrus.
