When users are configuring nRF applications they are given the option
to enable the DesignWare I2C driver. But they should not be given this
option because nRF SoCs do not have DesignWare I2C HW.
This commit hides the driver by default by introducing the config
option HAS_I2C_DW.

The Zephyr configuration system uses many different files in many
different formats. It makes it a lot easier for users to understand
what these files do if when we use the correct file extensions.
To this end we rename the dts.fixup files to the correct file
extension '.h'.
This is a breaking change for out-of-tree fixup files. Such files will
be detected and given an appropriate error message.

Move the SoC outside of the architecture tree and put them at the same
level as boards and architectures allowing both SoCs and boards to be
maintained outside the tree.
