The S3IP (Simplified Switch System INtegration Program) sysfs specification defines a unified interface to access peripheral hardware on devices from different vendors, making it easier for SONiC to support different devices and platforms. PDDF is a framework to simplify the driver and SONiC platform APIs development for new platforms. This effort is first step in combining the two frameworks. This specific PR adds the S3IP supported sysfs attributes in PDDF common LED driver.
