V2:
Add R-b from Mathieu
Add Rob in Cc for dt-bindings
i.MX8ULP features a M33 core + dual A35 core, M33 is kicked by ROM,
so like 7ULP, A35 only communicate with M33.
Based linux-next/master 6-22

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.
