i.MX driver changes for 5.6:

- Add i.MX8MP SoC driver support.
  - Allow IMX DSP Protocol driver to be built as module.
  - Add COMPILE_TEST for IMX_SCU_SOC driver to increase build coverage.
  - Print SoC type and revision in i.MX8 SoC driver, as this is useful
    information to have when looking through boot log.
