i.MX8ULP is a new SoC with Ultra low power support, it has a Cortex-M33
core and two Cortex-A35 cores. We need to add new configuration because
it could not reuse the previous i.MX7/8 configuration.
i.MX8ULP M33 core is kicked by ROM, it is not under control of A35 core.
So need to mark the method is IMX_RPROC_NONE.
