Any node which needs to generate defines from DTS must have a
"compatible" property, because the corresponding "constraint" is what
extract_dts_includes.py uses to match nodes with YAML files.
There are a few YAML files in the tree that list compatible as
"optional". Fix them.

Provide dts yaml bindings for 4 sensors supported by disco_l475_iot1
board:
-hts221, lis3mdl, lps22hb and lsm6dsl
Devices are denoted as i2c-devices and, as such, inherits from
i2c-device.yaml

Provide generic yaml description for i2c-devices such as sensors
New yaml binding category 'parent/child' is added.
It aims at binding two types of related node such as bus master and
bus slave.
In case of i2c-device object, parent property is 'bus' with value 'i2c'.
In the mean time, i2c node gets child property bus. Master and slave bus
values should match.
As such, 'i2c' node is bus master and 'i2c-devices' nodes are bus slaves

According to yaml syntaxic rules, 'properties' described in dts
bindings yaml files could be seen as 'mapping'(key/value couple),
instead of 'series' (list of single elements).
yaml 'mappings' will then be converted by yaml python library as
python 'dict' which will ease treatment (instead of current list
as were before this commit).
Same treatment is applied to 'inherits'.
script extract_dts_inlcude is updated to take change of yaml_list
structre into account. This allows some code simplification. Largest
impact is yaml_collapse function which works now allow complete
overload method on all the attributes of a yaml nodes.

Moved yaml files to be under dts/bindings and have the bindings try
and match the linux doc device tree binding dir structure as the
canonical binding reference.
