The mtk_iommu_mm_dts_parse will parse the smi larbs nodes. if the i+1
larb is parsed fail, we should put_device for the i..0 larbs.
There are two places need to comment:
1) The larbid may be not linear mapping, we should loop whole
the array in the error path.
2) I move this line position: "data->larb_imu[id].dev = &plarbdev->dev;"
before "if (!plarbdev->dev.driver)", That means set
data->larb_imu[id].dev before the error path. then we don't need
"platform_device_put(plarbdev)" again in probe_defer case. All depend
on "put_device" of the error path in error cases.
