i.MX SoC changes for 4.12:

Browse Source 
- A correction on mmdc_pmu_write_accesses event definition.
  - Add new axi_id perf command to support MMDC filter memory usage
    profiling.
  - Set correct SPI chip_select in platform device registration, so that
    spi-imx driver code can be improved to use chip_select directly for
    harwdare setup instead of indirectly via the cs_gpio mapping array.
  - Disable APIS bus supervisor protect for i.MX25, since the default
    configuration doesn't work for a few peripherals accessed through
    SDMA.
  - Add compatible check for the secondary generation of I2SE i.MX28
    Duckbill board support.
