[devices]: DellEMC [s5232]: PSU detection and default led state support (#3185)

*   [devices]: Add a new supported device DellEMC s5232f

    * Switch Vendor: DellEMC
    * Switch SKU: s5232F
    * ASIC Vendor: Broadcom
    * Swich ASIC: Trident3
    * Port Configuration: 32x100G
    * SONiC Image: sonic-broadcom.bin

    * LED support for s5232f
    * Changes Include ipmitool implementation for platform_sensors script is inclued in pmon startup
    * Added 100G,25G,10G configruation ( 100G is default).

* s5232[device] PSU detecttion and default led state support
