Subject: drm/amdkfd: convert KFD_IS_SOC to IP version checking
Git-commit: dd0ae064e71ada9cb2dd526607e140c7af690646
Patch-mainline: v5.17-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
Defined as GC HWIP >= IP_VERSION(9, 0, 1).
Also defines KFD_GC_VERSION to return GC HWIP version.
