[PATCH V2 4/6] dt-bindings: mailbox: imx-mu: add i.MX8 SECO MU support

[Peng Fan (OSS)]

From: Peng Fan <peng.fan at nxp.com>

Similar to i.MX8QM/QXP SCU, i.MX8 SECO MU is dedicated for
communication between SECO and Cortex-A cores from hardware design,
it could not be reused for other purpose. To use SECO MU more
effectivly, add "fsl,imx8-mu-seco" compatile to support fast IPC.
