[PATCH v3 0/4] mailbox: imx: support i.MX95 ELE/V2X MU

- Add dt-bindings
- i.MX95 ELE/V2X use same register layout as i.MX8ULP S4 MU, but
  the TR/RR num is different. To make code reusable and not add too much
  macros, add runtime detect number of TR and RR by reading PAR_OFF
  registers.
- Add i.MX95 ELE/V2X MU entry in driver
