arch/arm/dts: Add Turris Omnia device tree
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
