Subject: drm/msm/rd: Add chip-id
Git-commit: cfdc428d81a06d1b14dcbbe7aad285e076c9b917
Patch-mainline: v5.18-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 newer devices which deprecate gpu-id and do matching based on
chip-id, we need this information in cmdstream dumps so that the
decoding tools know how to decode them.
