Kumar Gala b109a0a9f7 dts: Add simple script to generate Kconfig.dts based on bindings 
Given binding dirs the script will generate a Kconfig.dts of the
form:

    DT_COMPAT_ADI_ADT7420 := adi,adt7420

    config DT_HAS_ADI_ADT7420_ENABLED
            depends on DTS_HAS_ADI_ADT7420
            def_bool $(dt_compat_enabled,$(DT_COMPAT_ADI_ADT7420))

Than a driver Kconfig can use these Kconfig symbols as follows:

    menuconfig ADT7420
            bool "ADT7420 Temperature Sensor"
            default y
            depends on DT_HAS_ADI_ADT7420_ENABLED
            ...

README.txt 

This directory used to contain the edtlib.py and dtlib.py libraries
and tests, alongside the gen_defines.py script that uses them for
converting DTS to the C macros used by Zephyr.

The libraries and tests have now been moved to the 'python-devicetree'
subdirectory.

We are now in the process of extracting edtlib and dtlib into a
standalone source code library that we intend to share with other
projects.

Links related to the work making this standalone:

    https://pypi.org/project/devicetree/
    https://python-devicetree.readthedocs.io/en/latest/
    https://github.com/zephyrproject-rtos/python-devicetree

The 'python-devicetree' subdirectory you find here next to this
README.txt matches the standalone python-devicetree repository linked
above.

For now, the 'main' copy will continue to be hosted here in the zephyr
repository. We will mirror changes into the standalone repository as
needed; you can just ignore it for now.

Code in the zephyr repository which needs these libraries will import
devicetree.edtlib from now on, but the code will continue to be found
by manipulating sys.path for now.

Eventually, as APIs stabilize, the python-devicetree code in this
repository will disappear, and a standalone repository will be the
'main' one.
