From: Peng Fan <peng.fan@xxxxxxx>
Similar to i.MX8ULP S4 MU, i.MX93 MU is dedicated for communication
between Sentinel and Cortex-A cores from hardware design, it could not be
reused for other purpose.
However i.MX93 S4 MU use separate tx/rx interrupt, so update
interrupts and add interrupt-names property.
