mailbox: imx: support i.MX8ULP S4 MU
Like i.MX8 SCU, i.MX8ULP S4 also has vendor specific protocol.
- bind SCU/S4 MU part to share one tx/rx/init API to make code simple.
- S4 msg max size is very large, so alloc the space at driver probe,
not use local on stack variable.
- S4 MU has 8 TR and 4 RR which is different with i.MX8 MU, so adapt
code to reflect this.
Tested on i.MX8MP, i.MX8ULP
