Subject: drm/msm/adreno: Generate name from chipid for 7c3
Git-commit: e2f76193958be91baed84583b2c638f8ca8b3bc2
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

Use a gpu name which is sprintf'ed from the chipid for 7c3 gpu instead of
hardcoding one. This helps to avoid code churn in case of a gpu rename.
