json-schema versions draft7 and earlier have a weird behavior in that any keywords combined with a '$ref' are ignored (silently). The correct form was to put a '$ref' under an 'allOf'. This behavior is now changed in the 2019-09 json-schema spec and '$ref' can be mixed with other keywords. The json-schema library doesn't yet support this, but the tooling now does a fixup for this and either way works. This has been a constant source of review comments, so let's change this treewide so everyone copies the simpler syntax. Scripted with ruamel.yaml with some manual fixups. Some minor whitespace changes from the script.

description:
|
|
The IPCC block provides a non blocking signaling mechanism to post and
|
|
retrieve messages in an atomic way between two processors.
|
|
It provides the signaling for N bidirectionnal channels. The number of
|
|
channels (N) can be read from a dedicated register.
