[v7,0/6] mailbox: imx: support i.MX95 ELE/V2X MU

Message

- 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

Changes in v7:
- Per Jassi, separate the patch to add of_platform_populate.
- Link to v6: https://lore.kernel.org/r/[e-mail]

Changes in v6:
- Drop node labels and add Conor's R-b
- Link to v5: https://lore.kernel.org/r/[e-mail]

Changes in v5:
- Per Conor, add restriction to sram property.
- Since i.MX95 MU has SRAM, we may not see it is compatible with
i.MX8ULP MU, so drop the fallback compatible
- Add R-b for patch 2&3
- Link to v4: https://lore.kernel.org/r/[e-mail]

Changes in v4:
- Address dt-binding comments in V2 from Krzysztof
- Link to v3: https://lore.kernel.org/r/[e-mail]

Changes in v3:
- Following dts coding style Per Krzysztof
- Add return type for init function, patch 2 is new
- Check return value when tr/rr is larger than 4 and return error.
- Link to v2: https://lore.kernel.org/r/[e-mail]

Changes in v2:
- Support sram property and add example
- Populate the sram node in driver
- Link to v1: https://lore.kernel.org/r/[e-mail]

Please ignore this V7 patchset, a patch was wrongly included.
