Maureen Helm eee3d8f566 drivers: sensor: Add sensor info iterable section 
Adds an iterable section in ROM to hold constant information, such as
vendor and model name, for all enabled sensor driver instances. This
will be used by the future sensor subsystem to enumerate all available
sensors in the system.
