Signed-off-by: Ramona Bolboaca <ramona.bolboaca@analog.com>
---
changes in v2:
 - reference /schemas/spi/spi-peripheral-props.yaml in allOf 
 - use unevaluatedProperties:false and remove additionalProperties:false
 - use generic node name and fix indentation in device-tree example
 - wrap lines nearer to 75-80 chars in documentation
 - add extra information to the description of the regulator
