This patch only adds the definitions and property reads, but the use of these properties will come at some point in the future when needed. Note a slight conceptual disconnect between the MIPI DisCo definition of a boolean property and the Linux implementation. The latter only checks the presence of the property to set its value to 'true', whereas the MIPI definitions allow for a property with a 'false' value. This patch uses the new introduced mipi_device_property_read_bool() to handle it.
