dt-bindings: mailbox: imx-mu: add i.MX8ULP S400 MU support
Similar to i.MX8QM/QXP SCU, i.MX8ULP SCU MU is dedicated for communication between S400 and Cortex-A cores from hardware design, it could not be reused for other purpose. To use S400 MU more effectivly, add "fsl,imx8ulp-mu-s4" compatile to support fast IPC.
