i.MX SoC update for 4.18:

Browse Source 
- A series from Bartosz to convert all i.MX plaform code using
    at24_platform_data to use at24 eeprom generic device properties.
  - Enable pinctrl driver support for i.MX6SLL SoC.
  - Clean up i.MX platform code using spi_imx platform data on outdated
    documentation and chip select array usage.
