The frdm_kw41z can be used as a standalone board or as an arduino
shield. Zephyr already supports the standalone configuration, this
change introduces support the arduino shield configuration.
In the arduino configuration, the frdm_kw41z operates as a ble
controller over serial hci. It can be attached to another board, such as
the frdm_k64f or mimxrt1050_evk, which runs the ble host.

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.

Cleanup unused leftover from shield development.
These flags are not actually useful, nor used as dts connectors
are sufficient to control board to shield binding is
operational and dtc provides meaningful error message
when this is not the case.

In order to provide a way to control boards/shields compatibility,
provide connector flags.
One should select this flag in Kconfig.board to state connector
compatibility for the board.
