there are 2 hubs to flush in the gmc, to make it easier

NAK, we can have more than just the two hubs.
See gmc_v9_0_process_interrupt:
if (entry->client_id == SOC15_IH_CLIENTID_VMC) {
hub_name = "mmhub0";
hub = &adev->vmhub[AMDGPU_MMHUB_0];
} else if (entry->client_id == SOC15_IH_CLIENTID_VMC1) {
hub_name = "mmhub1";
hub = &adev->vmhub[AMDGPU_MMHUB_1];
} else {
hub_name = "gfxhub0";
hub = &adev->vmhub[AMDGPU_GFXHUB_0];
}
Maybe put the name into the hub structure as well.
Christian.
