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.

QCOM SoCs have TSENS IP to allow temperature measurement. There are currently
|
|
three distinct major versions of the IP that is supported by a single driver.
|
|
The IP versions are named v0.1, v1 and v2 in the driver, where v0.1 captures
|
|
everything before v1 when there was no versioning information.
