This device tree is taken from mainline Linux kernel commit
7b7db5ab. Added is also a -u-boot.dtsi file with these additions:

  - aliases for I2C and SPI devices are added, because i2cmux and
    SPI flash doesn't work otherwise
  - spi_flash node has been added so that the new DM API works
  - the ATSHA204A node is added in the i2c@5 node
  - "u-boot,dm-pre-reloc"s are added in needed nodes for SPL
    build to work correctly
